I always use OEM Toyota pads (Toyota now sells a 'premium' Japan pad and a cheaper US-made discount pad). I have always found aftermarket pads to be noisy, but maybe it's just me. I have no idea if aftermarket rotors and pads work any better than OEM.
If you suspect your calipers are original, then reman calipers will help with side-to-side pulling when you stop. They are not super expensive on Rock Auto (Toyota's remans are back ordered apparently forever).
