If your wife likes the SD and rust is not an issue, you are home free! Prioritize the list of things to do, and tackle it at a pace that suits you. CLimate Control sounds like blower motor brushes and a rebuild of the Monovalve - piece of cake. My latest fix for seats if a layer of one inch high density foam beneath the horse hair and then the aerosol expanding insulation (not too much or the seat gets too stiff) in the springs. Great advice already on tranny (fluids, filter, mobil 1...) - include a fluid change of the differential while your at it. Window seal and tranny right away! It also sounds as if you want to check the ALDA tubes running from the intake manifold. Might result in serious power increase.
Wife loves the car... you've already won the battle. Enjoy the spoils...
