Just tape up the center of the rotor, so your wheel doesn't stick to the paint, tapeing the rotor surface, is completely up to you, if you don't, the brakes will burn it off... Just grab some brillow pads, and give the whole brake system a once over, and your paint should come out nicely. Somebody does make caliper stickers. I either read about them on the forums, or the mailing list... I'll try to find out who it was, and post it here.
Be sure to tape some newspaper on the fenderwells, so you don't get overspary on your car... if you don't decide on covering your rotors, your breaks are going to feel like their grabbing funny, but they'll get back to normal.
