John - I'm getting ready to do my headliner myself. Parts are about $50 at www.headlinerkit.com. Looks pretty easy to do. Bill R. just posted detailed instructions on getting it all off and back on, including the double sunroof. (Hell I thought I was the last one that still had a working double sunropof!) Search my posts, it was just yesterday I think. If the link is gone, I saved it as a pdf - just let me know if you want it.
The doors are easy. Some good glue (liquid nails, gorilla glue) does wonders.
Haven't undertaken it yet - re: my post regarding ANOTHER cooling problem!
