Hey Doug, Wayne has a very good book but I was refering to the factory manual, you can also go the the Porsche parts catalog (PET link below ) go to bottom og page put in your car and you will see selections for engine body ect, there are model specific drawings and parts listings this should help taking things apart.
I think most of the trim on the A & B pillars are glued BUT I have earlier cars, in general everything comes off before the headliner, and again headliner is done first.
