For year 2000, there are two different size brake pads on the front depending on the car. Models that came with 14" wheels stock, the brakes are smaller. Those with 15" wheels stock had larger brake pads. They have the same brake pads at the V6 model I believe. The rear drums should be the same.
I've never tried to change the power steering fluid before, but there's a tutorial on this site with pictures and all. The power steering uses Dexron III Automatic Transmission Fluid. Go to the
Camry FAQ and there is a link to a guide to change power steering fluid, photos and all.
