We're all forgetting that you need to either resurface the rotors or buy new ones when putting on new pads. If you just slap a set of pads on, they will wear out in half the time since they weren't allowed to "bed in" with the rotors. Resurfacing or "turning" the rotors should be $15-$20 each at auto parts stores that do that, or new rotors are probably about $30 each if you shop around.

I'm sure your calipers are just fine, severely abnormal wear on the pads would tell you if there's a problem with them.
