Its your car, so ultimately you have to do what your going to like with it, after all you have to live with it.
Personally, given that there are very few 2 door ghias left, I'd keep all the trim. Roof, badges, bump strips, the lot. If you get rid of it all then it becomes 'another' 2 door escort. The ghia theme would give it something different
I'd also keep the gold paint,but then I kind of like the more unusual colours
