As far as Naruto's skills, he just seems to be missing support abilities. Trust me, it would be lamer if he just learned a new skill that was stronger, then only started using that, then learned another skill that was even stronger than that, then started using only that...etc. He just needs small little techniques to give him small advantages here and there. Basically like Kakashi. Kakashi's uses Chidori the same as Naruto's Rasengan, but he does a lot of little things in between.

Anyway, besides Kakashi, look at the other characters. Sakura just punches. Shika just uses shadows. Kiba just makes the tornado thing with the dog. Naruto seems to be using more variety than some of these guys.
