Stuck rear calipers '89 200t FWD

[Cecilio Cerdan]

Hi fellow listers,
My 200 has been sitting at the same parking spot since I couldn't start it
for a while (month and a half) and have had little time for repairs. I'm
waiting for my spring break to fix it. My apartment manager wants me to move
the car to another spot as they are repaving. Got my friends to push it...
and surprise!! it is like nailed to the floor. The parking brake was applied
all this time (big mistake, I know). So I've taken both rear wheels off and
found out that even lowering the lever the pads are badly stuck to the
rotors and the caliper as if all were one piece and they're all rusty. I've
tried to take the pads out following Bentley, but it is the 1st time I do
brakes and the bolts didn't move at all. My questions are 1.- Is there an
easy trick to get the rear wheels moving?  2.- How much it is reasonable to
pay at a shop for new rear calipers/rotors/pads? 3.-Should I try doing it
myself, or it is a real difficult task for a beginner?
Sorry for the long email-Thanks for your time and help.
