I've actually never done the rear pads, but the front ones are really easy because they go in through the top of the caliper. When you change them, make sure to use anti-squeal paste, and remove and replace one pad at a time (as opposed to taking out both, then trying to install both). This makes it easier to compress the calipers to get the pads to fit. Everything else regarding the guide pins, retaining clip and wear sensors should be pretty obvious. Also, it doesn't take very long. Good luck.
