I'm currently running ceramic pads on slotted rotors, and they don't brake as well for the first stop in the morning (I have a 1 mile 7%+ downhill grade to start with), but once the first major braking is done, I swear by them. The rear brakes are just semi-metallic riveted shoes (8" drums). There is a huge difference for stopping power between the OEM 1st gen brakes and the new stuff. I rarely lock a wheel now, but will stop a whole lot faster. There is also zero brake noise (another good thing about ceramic). Dust is there, but it's a lighter color. As far as wearing out a stock rotor, that really depends on what the rotor is made of; I would say the stock ones are fine, as semi metallic is just as hard as ceramic.
