Is "where you been" commonly used to ask about whereabouts? "Have" is omitted here, right?

Yes, that's correct. It's a more casual, colloquial way of saying "where have you been," especially used to ask where someone's been after you've been looking for them. Ex: Hey man, where you been? I was looking for you. Ex: Where you been? Haven't seen you in a while.
