As far as i understand the part that returns the caliper is the square o ring that seals the fluid, it deforms when the brake is applied, stretches whilst holding on to the caliper and returns to it's original shape once the pressure is released,thereby providing the small gap to free the disk, it may have been affected by the heat and may have to be replaced together with a good clean of the caliper and housing to ensure smooth operation.

You are right. This is why it is important to clean the pistons "spotless" in the caliper before retracting them to fit new pads.
Also, if it is a floating caliper, the slider pin should be cleaned and greased.
All this will help the brakes not to drag.
Regarding the noise, it is usally due to dirt on the disc or pads surface. Use some brake cleaner and it should improve, but regular use of the bike will definetly help.
