Went on the Power Stop website and filled out the questionnaire, and for a 2008 4Runner they recommend:
Power Stop Performance Brake Pads Rotors Kit KC2405A-36
Power Stop Extreme Truck & Tow Brake Kits | Power Stop
With the red powder coated calipers, AutoZone has the rear kit for $341 and Summit Racing has it for $309. I'm going to replace just the rear for now, and will likely do the front in the near future to avoid shelling out $800 for both front/rear.
