I like the plain jane Brembo rotors
I've had my plain Brembo rotors (not slotted or drilled) for about 2 years now. No problems with warping whatsoever. They were cheaper than replacement Yota rotors. Auto Parts Warehouse or one of it's associated affiliates perhaps Brake Warehouse, has good prices and free shipping-which could add up for something heavy like rotors.
For pads I went with what the dealership called "upgrade OEM pads" on my 99 which I believe became "standard pads" on 00-02s.
Verify your rears are doing their fair share of the stopping...good time to bleed the fluid and replace.
