recurring brake rotor problem...

I think a good place to start would be talking to the shops and guys that actually race and have tried numerous different setups. RRE and Archer both highly recommend the Porterfield R4-S (carbon/Kevlar) for street, autocross, and light-duty track DSM's. You can also check out the EBC Green and Red compounds, the recently revised Red pads with Kevlar are supposed to be very good but historically EBC's offerings haven't been all that spectacular. If you're looking to keep things cheaper though you can just get some Metal Master Semi-Metallic pads. My advice though is to stay away from anything Hawk.
