A few years ago there was a series of magazines called something like 'Star wars Technical Journals' that had lots of equipment pics and info. I have one at home and can get you more info maybe tomorrow.
Also try your local Barnes and Noble sci-fi section. There have been at least a couple of big books with 3/4 and cutaway drawings of ships and such. These might be the same one djmodels was talking about.
