Not necessarily "useless", but he is less powerful without Kyuubi.
Kyuubi
Yup. Because of the seal, Naruto doesn't have access to all of Kyuubi power and Kyuubi can easily regenerate all his chakra. He probably has other tricks up his sleeve.
Naruto's mother (Kushina Uzumaki) was the jinchuuriki before Naruto.
The whiskers on Naruto's face is the result to the exposure of the kyuubi's chakra.

Um...O.o No. Kyuubi is the title of the bijuu sealed inside of Naruto. Naruto's mother was Uzumaki Kushina.
Chapter 299 was the first time Naruto went kyuubi.
There is a Kyuubi Naruto on Naruto Arena. You must complete a certain Mission first. I'm pretty sure it's B-rank.
Without looking it up, is that the episode Naruto uses the rasen-shiriken on Kakazu? If it is, then I'm guessing you've noticed his eyes looked like the kyuubi's but blue. In my opinion, I think he was just using some of the kyuubi's chakra to use that attack, but not changing into the kyuubi form.

the kyuubi is the nine tailed demon fox yodaime sealed within Naruto.
you cant
Naruto is NOT Kyuubi! Get this into your head! He and the demon fox are ENTIRELY different! The villagers know that the fox is sealed into Naruto but they treat him as an outcast, not the hero keeping Kyuubi from getting his revenge on Konohagakure no Sato (Leaf Village)
When he is really mad.
The 9-tails or Kyuubi.
