Have you taken him to the vet? He should get checked out and they can probably give him something. When I got Vlad, he was infested with fleas. I think he must have been about 10 weeks old when I took him to the vet and they gave him a pill that killed the fleas on him within 2 hours.
As for clawing, a little trim of his nails might help, and getting him a scratching post. When he starts to scratch at you, just divert his attention with a toy.
I've slept with all mine since they were kittens. Oksana was the smallest when I got her, she was just about 8 weeks old. I just made sure she slept next to my pillow.
There are only two rules at my house: House rule #1. Cats rule. House rule #2. See rule #1.
