Not sure of all the answers to your Q's but as far as the piston sticking and the actual bleeding process goes, try these
1) - With the caliper removed from the disk, place a zip tie around the caliper so that it passes bewtween the two piston on the inside. You want to position it so that it prevents the free moving piston from actually moving. Once in place you can slowly actuate the rear brake which should ease the non-moving piston out. Smear the piston walls with some copper grease, press it back in and repeat the process several times. Should free up the bugger once and for all.
2) When bleeding the rear brake it has been suggested B4 to do this with the caliper removed from the disk and with the bleed nipple pointing upwards - i.e. at it's highest point to aid the removal of air from the system.
Hope this gets you going mate
