I mean, based on what was said in the first episode alone, we now know what was locked inside Gaara is the same type of creature Naruto has inside him. And look what happened when Gaara lost himself in the the power. It was at the point where he wasn't even the one controlling it anymore, and it was more or less using him as an avatar so to speak.

I can see why Naruto wouldn't want to use the Nine Tail's power. Maybe he knows about losing himself to the demon? Or, maybe he just wants to use his own power, and not rely on anyone else but himself.
Actually, from the first part of the episode I thought Naruto was able to control the Kyuubi. He was talking with it and wasn't scared at all. The Kyuubi said "let's show them our power" which I assume meant Naruto is able to fully harness the Kyuubi chakra inside himself.
