NB is having problems, so for the times I can get on I'll try my best to train you alright. Anyway, you did fine. Here's my interpritation on the concepts that will do you good to keep in mind.
Shinobi/Kunoichi: Shinobi and Kunoichi are those who practice the art of Ninjutsu. In order not to confuse, I'll keep this in terms of the RP and in the Narutoverse. Generally you'll see shinobi from villages, clans, or solo. Shinobi in villages act as military soldiers and they carry out tasks for the village for payment. There are clans within villages (outside as well) and generally clans protect secret techniques, fighting styles, and or Kekkei genkai which are genetic based techniques. Solo shinobi may be from clans they may have trained indiviually but they may have also once been a part of a clan or village and have defected for breaking the village/clan laws. However the idea behind shinobi is that they are warriors who practice the arts of ninjutsu for whatever reason. They have their own philosophies, desires, ambitions, goals, motives, etc. They dedicate their training to something and as such depends on how they act. Traditionally shinobi are warriors that do what they're told without hesitation and without question. However shinobi are sentient beings capable of thinking for themselves. There are traditions that are to be upheld but you can't hold everybody to the same exact standards, which is why there are varrying personalities and tendencies of different shinobi and, often enough, reasons why some shinobi are defects.
Taijutsu: Though you are right that it's hand to hand combat, you are wrong that it doesn't require chakra. Taijutsu doesn't require chakra in the same sense as Ninjutsu and Genjutsu, taijutsu utilizes chakra in the sense of one's physicality. Their power, speed, endurance, physical feats all of this utilizes chakra. Taijutsu (in the general sense) doesn't require one to mold chakra as one would do in nin or genjutsu, but they use the physical properties (primairly yang) to push their limits of strength, speed, and endurance. The way shinobi find themselves exhausted after using multiple ninjutsu or genjutsu techniques is the same for how they become exhausted using taijutsu, they're using their energy.
Genjutsu: Genjutsu=illusion based techniques, techniques that attack the mind rather than the body. My personal favorite style of fighting (highly underrated in the RP) as I believe destruction of the mind is the most dangerous key. If you can control a person's mind, you can control them. The brain is the control center, the function of your entire body. It even controls your physical being if you think about it. If you destroy the brain, you destroy your opponent. You're opponent can't do anything without the mental capacity to think, even reflexes and impulses are controled by the brain. My point being, as genjutsu attacks the brain, it attacks perhaps the most vital point in you're body. You can render your opponent insane, cause them incredible amounts of pain without harming their body directly, torment their mind in various other ways. Mental incapability is just as, if not more affective than physical incapability. You are right about how gen works though, it disrupts the flow of chakra to the brain to allow the user to manipulate it to cause varrying affects.
Ninjutsu: Refers to a few things. As you said they are Ninja Techniques...however what specifically are ninja techniques? Don't Ninja use taijutsu and genjutsu as well? Ninjutsu refers to the ways of combat practiced by shinobi, just as Bushido and Iiado are the ways of the samurai (Bushido being a term like Chivalry, an honor code not necessarily a fightin style). In the terms of specifics ninjutsu utilizes chakra to create tangible affects as you said, but they can be for attack, defense, counter, or supplementary purposes alike. Ninjutsu like everything else requires chakra. You mould chakra to create the tangible affects.
Chakra: Is the life source of all living things. Everything from people, animals, and anything in nature poesses energy. To focus primarily on the Chakra instead of getting into Nature energy, Chakra is the equivalent to Xing (Japanese)/Chi (Chinese). It's inner energy and it's ballanced by physical and spiritual properties. Every form of jutsu (Tai, Nin, Gen) utilize both Physical and Spiritual chakra. Lets talk on Physical first. Physical chakra within Taijutsu refers to what I said earlier, strength, endurance, speed, and general physical properties. You're physically exerting your body and that requires chakra. In Genjutsu, believe it or not, you're physically using your chakra to disrupt chakra in the brains of your opponent. Though the affects are illusion based you exert physical use your chakra to channel it to your opponent to cause them illusions that affect the sense. See how that works? In Ninjutsu, as I said, it creates the tangible affects of the specific techniques. Now for spiritual, more difficult to understand the relationship between of spiritual chakra and Taijutsu, but not impossible. Physical discipline, pain thresholds. Look at Yondaime Raikage A, the man who cut off his own arm and didn't bat an eyelash. I practice martial arts and I understand the underlying affects of that. Through mentally calming and balancing yourself you can regulate pain in the sense of how it affects you. Shinobi can fight through pain and that is how spiritual chakra translates to taijutsu, mental balance and controling pain. For Genjutsu, the Spiritual chakra (Yin) comes from the affecting the mind. Once you have disrupted your opponents's chakra the spiritual affects that deal with the mind kick in. The second Mizukage professed his skills as a Yin Release User which meant Genjutsu so essentially the balance between Yin and Yang for Genjutsu is primarily Yin. For Ninjutsu you need the actual affects of what you're bringing into reality. You use the imagination/mind to concept the technique and then exert it physically and create tangible affects.
5 Elements: The Five elements or five nature releases are chakra within your body that hold to a specific element. The basics are Water, Fire, Earth, Wind, Lightning. Shinobi have a primary affinity, a nature chakra that is stronger within them then the others. Through training shinobi can learn to unlock and master other elements. Though it's a more difficult feat to accomplish. That being said, the more elements a shinobi possess mastery over generally means that shinobi is skilled because of the time, effort, and discipline they must of endured in order to master the other elements. The Five elements also have relationships to each other in the cycle of strengths and weaknesses (Example: Wind<Fire<Water). They also have relationships in conjunction and unity with one another to create various other affects (Example: Wind+Fire=Stronger Fire | Fire+Water=Boiling Steam)

Next thing I want you to do is to sit and meditate. In order for you to come to understand, control and manipulate lightning, you must learn to feel the lightning chakra inside you. Meditate deeply on the aspects of lightning, and feel how it connects to you and your chakra. Focus on the savagery of lightning, the speed, hyperactivity, the uncontrolable entity. All these aspects are within your chakra, connect with them
