I don't think that there is a good manual on the 960/90 series cars other than ordering parts of the factory manual. Chilton makes a so-so one that includes all the cars in the 90s, so you can imagine that its fairly general. Some people have recommended the Alldata CD (but apparently not the CD that is for sale on ebay). The Brickboard FAQs are good, and you should review the 960/90 section: http://www.brickboard.com/FAQ/700-900/960_90Info.htm

As for maintenance, you should definitely use synthetic oil. I use Mobil 1, but AMSOIL is also good. I also think you should flush the transmission and use synthetic ATF. I have AMSOIL in my tranny, but Mobil 1 is also fine. The transmission is expensive, so you should make sure it gets regular flush and fills.

Don't know about the windows. The oil change to synthetic may help the engine "ticking." I use Castrol LMA for brake fluid. I think its DOT 3/4.

The FAQs have an excellent list of things to do after buying a used car. Pay particular attention to the timing belt, radiator and hoses. Take a look here: http://www.brickboard.com/FAQ/700-900/HighMileageVehiclePrevMaint.htm#Preventive_Maintenance_After_Purchase

Hope that this is helpful to you. Enjoy the car!
