I couldn't feel your pain more. I just spent over a week patching a ceiling in an investment property over a drippy 60 cent copper T. It was a major "f-it" moment when I decided to skim coat the entire ceiling to get rid of the imperfections... still took two or three touch-up sessions after that. Finally got it to near perfect today... I sure hope nothing else leaks.
Your setup is very interesting... I have never heard of ceiling radiant heat! Seems like the fact that heat rises makes this a bad idea. If you keep it I would have ceiling fans set on a very low setting blowing the air downward when you're using that system. I have heard of plenty of heat sources buried in floors, but neve in a ceiling. Is it controlled by a thermostat in the bathroom? Maybe it's actually a heat source for the upstairs instead. All of that said, different things are done in different areas of the country.
There is a really good forum dedicated to HVAC... run a Google search for hvac talk and you'll find it. It's a very active forum, and the guys there can give you good advice. Depending on your budget, I think your most economical option (for operating cost) is forced air dual fuel in your climate, but the ease of running duct work has a huge impact on what that would cost.
