Ok, Ive heard of cats doing this, but is it normal?

My kitten "kneads" everything. His food when he is eating it(and he eats a lot!), when I pet him he will knead me or the air. When he is sleeping, he may knead what he is sleeping on or the air.
He also meows a ton. Ive never owned a cat before, but Ive known people who have and they all have never seen such a talkative kitty.

Are these signs of any sort of behavioral problem, or do some kittens just do this kneading thing for awhile.

Oh yeah, sometimes if he is on my lap, he will bite me (Possible trying to nurse?) and kinda just hold his mouth their.

Lets see, he is about 9 - 10 weeks now.
