My cat Sky also likes to bite me. I think that when he was a kitten someone must have used their hands to play with him so he thinks that hands are toys. I would recommend that when your cat bites you that you say "Ouch!!" and then act like you're in pain. Then walk away from your cat and ignore her. Hopefully she'll learn that this is inappropriate behavior and that she'll be ignored when she does this. Good luck and please keep us updated.
I also agree that you should never hit an animal because they don't understand why you're hitting them and it only causes them to become afraid of people and not to trust them either.
