How do I sync only contacts with phone numbers from address book to my iPhone?

I got my iPhone today (yay!) and everything about it is fantastic. But my address book has bajillions of names in it with no contact information, because all of my ichat buddies have cards in Address Book which sync to the phone as just a blank card with their names. How can I set up Address Book so that it only syncs cards with phone numbers (or other specific information) and not every card?
