Frank I think you have bought a very nice example its looks great in the photo's and the issues you have identified are all sortable (if that is a word lol) with time and dedication that us Classic Audi types tend to devote our passion.
Help is always at hand, look at the help Ben gave with the door lock problem, he is a great member and has helped me a lot in the past.
I also think the fact that the wife can't drive it is an advantage, just don't tell my wife I said that lol
