Sven,
very nice work.
About your headlights...
I have a '91 Nissan 240SX hatchback, which is very similiar to your Probe.
When I fist got it in '97, the headlights started acting up (sticking up, etc) and my wife scored me a set of recessed headlights from Japan.
I was looking on line for anything similiar for your Probe, but couldn't locate any, however, you may be able to get a set for the S13 model 240sx and alter them to fit your car, then make clear plexi/lexan covers for them:
