You don't need to resurface rotors when you change pads but some people recommend changing your rotors when you change your pad.
Personally I've always felt that a proper bedding will get rid of previous pad deposits. 4 or 5 panic stops from 80mph outta do it. Then you need to make sure you don't completely stop and rest on the brakes while the rotors are still smoking or you're likely to melt the pads to the rotor, that's typically what causes the vibration many attribute to a warped rotor.
