My right front in my NA stuck on once. The piston had started to rust and jambed itself in the bore. I was lucky in that the bore wasn't corroded so I just replaced the piston and seals and all was well again.

Initial,
Sounds like the rear brake has seized on the slider pin. You will need to dismantle the brakes. Hopefully the slider pin has not rusted to the point that it cannot be separated from the rest the brakes. Mine was, and even with the ‘BFH’ it would not budge. Cost me $160 for a 2nd hand rear brake unit from the wreckers.
Once you have repaired/replaced the slider pin it would be a good idea to do some preventative maintenance on all of the brakes. It will save you much grief down the line.

The only thing that confuses me is that the brake came unstuck and is now fine. If the slider pin was seizing it up, would this still be the case?
Yes, it can stick and then release. It would be an indication that the slider pin needs to be greased. Best to get in there and do some maintenance. If it doesn't bite you now, it will later on.

when it comes to taking apart a rear brake disk im working in the dark
Best to get someone who knows what they're doing to help you out then. The last thing you want to do is run out of brakes because you installed something incorrectly.

If you take it to a general mechanic then go to Miata.net and download the instructions on how to rebuild the calipers. The Mx calipers are different to the average cars and can be damaged if not treated accordingly.(I.e tryig to push piston back in with a vice is a very very bad thing.)
I rebuilt my calipers as one was doing what yours are. it was the lever that the cable attaches to that was binding in the caliper housing, not the slider pin inside.
