[V8] new v8 owner new to the list

[John Bysinger]

I just joined the list and thought I'd introduce myself, as you'll likely
see me asking questions about the V8 Quattro I just purchased. :)

My name is John, and last friday I just picked up a 1990 V8, in really good
shape.  It's got 121k miles on it, 3.6l, auto tranny.  It does not have the
UFO brakes, and yes, I'm already making plans to change out the timing belt,
water pump, and misc fluids / tuneup work.  I figure start fresh and
check/replace everything that could go wrong.

And now on to the new-to-V8 questions...

First I've got a chipped/cracked headlight, found a couple of places online
that have new ones, but thought I'd ask for recomendations on parts shops on
here first.

Also the drivers door lock is busted, I pulled the door apart and found that
it's just the connector on the key barrel itself where it connects to the
linkage rod, anyone come across this before?  I see a couple mentions of
parts v8's on here, anyone have one that they'd be willing to sell me a
handle off of?

As far as the timing belt goes, I was looking at the kits + rental tools off
of audiquattroparts.com.  Any good/bad experiences with them?

And lastly, my heater motor is dead, I found this online and was planning on
using it as a guide for replacement:

flaps/valves functioning with the controller, I take it this is pretty
common?

Sorry for the long winded initial post but new car = new questions :)
Thanks to any and all help, and hopefully I'll be able to help you all out
in the future as well.
