Okay, I know this may sound a little harsh, but I have this thing about biting, I HATE being bitten, so when my son was about 8 months old, and he tried to bite me, I bit him back. Not hard mind you, just hard enough to let him know that it doesn't feel pleasant. He did it mabey one more time, and I bit him back again. Again, not hard, just enough to let him know that he he didn't like the feeling any more than I did when he did it to me. He hasn't bitten me since. I did the same thing when he got a month or so older and decided he wanted to start pulling my hair. I don't think babies realize how uncomfortable these things are until they are done to them. So, I recommend letting him know that these things are very unpleasant for you. It worked wonders for me. My son is almost 5 years old, and he's never been a biter or a hair puller!
