In the meantime, while you're trying to change his behavior, why not try doing something to blunt his claws? regular clipping keeps them a lot duller, just watch out for the quick. Or you could try the plastic sheaths that glue onto the claws, although they do fall off eventually. It won't help with the biting, but at least you won't be getting scratched.
