What I would do is get a good set of pads that are non-OEM (Akebono, Hawk HPS, etc...), then before putting them on, have your front rotors turned. If they have a lot of metal left, this should result in a nice, flat, rotor. Then follow the instructions with the pads for the "nbedding process and you'll be all set.
I had warping issues in Europe, where 125 mph to 60 mph slow downs will heat op the rotors a bit. I had a Volvo V70, and I warped the OEM brembo rotors after only 10,000 miles. Once I replaced them with Power Stop rotors, and matching pads, all was well. Just my experience.
