Just a few comments and observations--Why use a torque wrench to loosen bolts? They're not designed for that, and the only advantage here is the extra leverage you have for loosening. And, you didn't mention it, but just wire brush bolts before torquing- no lube or anything else that would affect torque specs. When replacing pads, it's always recommended that you start at the wheel furthest from the master cylinder--RR, LR, RF, and then LF. And before replacing pads, PLEASE loosen/remove the cap on the master cylinder, and put a "diaper" under it to catch the brake fluid displaced by the new pads (if you don't, you can blow the cap off and spray brake fluid all over the engine, etc {I admit I've done this}), especially if you're doing all four brakes.
