Sorry mods for not merging, but I had these thoughts at two different times.
Genin is just a rank. Look at the Genin. Naruto, Sasuke, and Kabuto.
Naruto going through the Chunin exams would be fun just to show him kick some ass. He probably wouldn't even need Sage Mode. It'd be pretty funny though if some Genin tried to attack him and he used Sage Mode to rip out a big ass tree and they'd be like

?
Sasuke going through it would probably get him kicked out because in his current psychological state he can't tell the difference between a handshake and an attempted murder. Not that he is actually a Konoha citizen, but if he was and had his current powers...Konoha would have to sell him.
Naruto will probably jump from Genin to Hokage. I haven't looked at Naruto as a Genin since part I. He's obviously the most powerful ninja in Konoha.
To the guys who say that he isn't smart, check his DB stats. He's as smart as Sasuke, and only half a point below what Kakashi was in part I. Kakashi had a 4 in part I, Naruto is at 3.5 which is above average.
Hokage are technically just the strongest people in the village who are the best suited for it. So Naruto could very well become Hokage in the next 100 chapters without going through Chunin and Jonin ranks. Hokage is a permanate title, even if someone else becomes stronger and better suited for the job.
