I really appreciate the effort you've put into your reply and you've got most of it covered. Although, I need to explain some things to you. The information you've got about Smoke Ninjustu in Narutoverse are from
Naruto Fanon Wiki, which is not a reliable source because it is a place where people create their own characters and abilities and actually make an another, greatly different universe. That's why for collecting information, you should use
Narutopedia, but then again, you oughtn't to copy it literally.
There was no Kemari and the use of cigarettes and pipes to perform Smoke Ninjustu in Naruto. It was seen in anime-only, Three-Tails Arc, where

used it. It is extremely important for you to understand the fact that smoke isn't really an element. It is only an advanced form of ninjustu that uses preexisting smoke to create attacks. That means that you aren't able to, for example, transform your body into smoke, or freely breathe in smoke, because smoke is still a matter that's strange to your body, because you haven't really mad eit. Also meaning, every bad influence that smoke has on other people, affects you as well. You being a Smoke user, does create some kind of immunity towards Smoke because you use it all the time, but it all remains in theory and is still not enough for you to avoid the same consiquences while breathing it. You understand Smoke's most used properties; making a person cough and greatly restrict its vision. That's why it's good to have sensory skills with Smoke, because they're essential while using it. A fact that it has connections with Fire Release is true, but we Smoke users rarely use smoke that's made from fie to create our ninjustu. We use tools, such as gas masks, smoke bombs, and wrist launchers the most. Although, Smoke Ninjustu doesn't increase the power of Fire Release, nor it will be set on fire with the usement of Fire Release. But you can play with smoke made from fire later, when you complete Smoke Ninjustu trainign. That's another things that's good about smoke, you have many possibilities with customs.
Smoke bombs:

are the most primitive ways of creating the preexisting smoke that's required for the usement of Smoke Ninjustus. They're not the best solution because you mostly need to throw it with your hands at the opponent and that takes much time and isn't really practical - you can only throw a limited amount of smoke bombs at a single moment and if you throw more of them, you lose precision. Using a smoke bomb for Smoke would work something like this: before you throw a smoke bomb, you fill it with your chakra, so that you have control over the smoke that's created after it explodes. But smoke bombs are rarely used.
Gas masks:

becomes your best friend once you start using Smoke. Not only that it protects you from bretahing smoke and allows you to move normally in the environment affected by it, but it aloso is a tool used for producing smoke. So, besides a ventilator, it has a mechanism for creating smoke. You use your chakra to trigger the mechanism in it and make smoke to start going out of it. Gas masks are used even more rarely for creating smoke because there is an even better way. But never the less, it's quite essential for you to wear it while using Smoke.
Wrist launchers:

is the most popular tool for creating smoke and is also the best because it's the fastest and most practical. For most cannon techniques, in their destriptions, it's even required for you to use one. As you can see in that link, wrist launcher that was used in anime is too massive and even resticts your movements. That's why Typhon came up with a solution for that problem. It's much better for you to use a one-barreled wrist launcher that's tight to your forearm. That type of wrist launcher refutes most disadvantages that the original one has. The principle of using a wrist launcher is easy; you use your chakra to trigger the mechanism in it and while the smoke is going out of it, you mix it with your chakra and gain cetrain control over it.
Please ask questions if you do not understand something. If everything's clear, we can starts with the techniques. ^^
