Don't go with drilled rotors for the same reason you shouldn't go with them on a race car: Thermal Capacity. You'll need all of it the one time you need to make that emergency stop!
PF pads supposedly work well, but I've had problems with my brakes since I installed them. I don't think it is the pad, per se, but something ain't right. This weekend when I did some work on the trailer, the van stopped better with the trailer attached than it does without!
