beo

I'm going to the junkyard to pull a bunch of parts off of an A4 for my 96.

included in my list are the following:

door motor window
wheel bolt caps
door speaker
front underbody engine shield
armrest
rear passenger interior lamps
heater/ac led display
cruise control stalk
cruise control computer controler
sunroof rheostadt

QUESTIONS:
1) What tool do I need to purchase to remove the steering wheel to obtain the cruise control stalk?

2) How do I remove the sunroof rheostadt without destroying my interior?

3) anything else I should get?

4) side question -- how do I fix my drivers window from wracking within its frame and overloading the window motor?
