I had to use a rubber mallet many times to get the caliper bolts loose. Once off the car, it was really tough to make everything go together properly.

Yeah, I agree. It's do-able for the beginner. (I am one and did mine using the web and the forum).

Since you didn't know about pb blaster, I would also recommend you buy a Flex Handle Ratchet Set like

The short stubby one is really good for getting at the guide bolts.
The variable size length ratchets let you get the most turn with a neck that bends so you can get at the caliper bolt. The ones in the rear of my E90 330xi were challenging to get to with little rotation room.
