oh yeah, the tail light condensation is a very common problem, if you do a search for it there are multiple ways to remove it at no cost. And the sunroof, there is a plastic cap in the roof around the light somewhere if you pop it off there is a clutch nut for the sunroof, try tightening it and see if that helps you with the sunroof problem, that and cleaning the tracks, lubing it up should fix the problem, and as long as you have basic tools that will also be a no cost solution. You can't beat free.
