On the broken caliper bolt, I recommend drilling it very carefully with a size that is small enough to miss the threads, then tapping the hole. If this fails you can always use the heli-coil as a fall back position.

The one thing about brake pads is always use the same pads front and back. If you don't, one end will lock up first and compromise your stability under heavy braking.
