1) In last chapter Naruto's clones were capable of by themselves to use Odama Rasengan to bust the forest, Naruto is capable of casting a mini-rasenshuriken with 1 finger. So no he doesnt require clones anymore to perform Rasengan it was said over and over again that the reason that Naruto's chakra control was poor was that Kyuubi is messing up, now Kyuubi as he cant mess with him anymore since he attained the RM and the fact that he is on the verge of allying with Kyuubi will only make his chakra control better.1. Do you understand what Chakra Control is?
2. Ninjutsu, not just a Rasengan. He needs to show more than just different versions of a Rasengan.
3. Doesn't matter, he sucks at Genjutsu now.
He has these things to worry about before trying to learn Fuinjutsu.
Who the hell is talking about the Sharingan?
2) Again as I said he needs versatility and variety, one thing is to say that and another to say he has BAD Ninjutsu, again he doesnt, he has the most powerful fuuton jutsus and can spam them which allow him to take down a forest, he is accessing a Bijuu nuke as well. Yes Naruto lacks variety, but it is just that, lack of varaition it doesnt mean he is BAD at ninjutsu at all.
3) I see your point here however this is something that is automatically going to be solved when Kyuubi is partnered. And yes Jiraiya taught him to dispell genjutsu, just that he wasnt able to do it back them because of his poor chakra control when the Kyuubi was messing up.
