Mine was a biter too! I used Bitter spray on things I didn't want him to chew and said "no biting!" when he would rough play with me. He is about 19 months old now and he still play bites (mouths) with us and knows if he is getting too rough when we let him know and licks us in apology afterwards.
I like the advice of an "OW!" noise, and I think adding "no biting!" is good too. My dog now knows that no biting applies to clothes, blankets, etc. when "no biting" is used.
