Welcome to the board. I've done a Ghia top before, including headliner and stuffing. It can be done, provided you have a good bit of time, a dry place to leave the car, a set of factory directions or the Bugstuff video, a little skill with fabrics and lots of patience. It took me two weeks of afternoons and at least two years off my life, but it turned out well.
If you've got the money, Grants on Broad St. is the place to go.
As to paint, I just had the guys at Express Auto Body on Rossville Blvd do my Spitfire and it was a good job for the money (around $700 with a little bodywork). You might check them out.
