I got my rotors from rotorpros.com. They use Centric blanks, which are supposed to be pretty good.
I don't remember exactly how much. Seems like about $400-$450 for all four rotors.

Pads are Bendix, but I have had good luck with others. I really can't tell whole lot of difference with pads.

Check the FTE sponsors. A few of them sell rotors.
