That is exactly going to happen to Neji. He will be hit by Sasuke's signaure move, Chidori. Put that in your head.

In addition, Sasuke was complaining about not being able to remain in that second seal form almost as soon as he entered it. At that point, Naruto had already been all Kyuubi'd out, and showing Sasuke how strong the pimp hand was.

So, I am not totally understanding your equation as to how Sasuke outlasted Naruto.
Let me get this straight. Naruto stayed longer in Kayubed state and Sasuke just enterd his lv2 and quickly finised Naruto.
Seems to me Sasuke knows how to use his lv2 seal well and did outlasted the battle.

Otherwise, Sasuke would have known which mirror Haku was truly in from the beginning
Sasuke couldnt tell which mirror Haku was in b/c they only reflected him, his bloodline ability, but when he came out to attck, Sasuke slowly managed to discover his movement from one mirror to another.

Kidoumaru is much more suited for combat against Neji. So, while Sasuke may be so much more powerful, his fighting style isn't adapted to overcome Neji.
Adapt he will. I dont think anyone can deny that Sasuke was rookie no. 1 and is intelligent. Long range or short range battle, Sasuke can fight both. He is more powerful (you said it yourself), more equipped and can adapt to the long/short rane battle modes.
