ProV1, only replace the rotors if they're worn to near the minimum thickness stamped on the OD. Yes, you'll need new wear sensors; but reuse the existing pins. I recommend Textar brake pads if buying them online, or use original braked pads from the dealer. You can use a C-clamp or pliers to push the pistons into the calipers so you have sufficent space to install the new brake pads.
