Rotors do not warp. Pulsations or rotor thickness variances are caused by uneven pad transfer.

However, it is very important when changing pads to get all of the old pad transfer off of the rotor, so the new pad compound does not conflict with the old compound, and cause nasty things like severe rotor grooving and permanent damage to aluminum wheels. This is done with brake cleaner and some sandpaper.
for most commuter cars, it is not much more money to just replace the rotor. I certainly never turn rotors on my racecar.
For those of you going to midas for your brakes (and probably paying $300+ for a brakejob) you would be surprised how easy it is, and how few tools it requires to do it yourself. For well under $100
