Ok how do you properly take off the headliner on a TA without T-tops? I don't want to screw anything up so I am asking before I try. The one in the car is getting pretty bad and I rather just not have a headliner than having one that is sagging on your head

No one knows this?
Pretty straight forward. Remove the dome light,sunvisors and all trim plastic holding it in place. Remove the rear speaker panels and the rear trim piece just in front of the hatch along with the top screws in the rear side panels. Then lower it down while carefully popping the plastic clips in front free and maneuver it out of the car.

A story on doing a headliner repair to an 88 GTA (No T-tops) will be out in the November issue of High Performance Pontiac. If you can wait that long, it will be on newsstands in a little over a month.
I guess I will wait for the story to see what they have to say. Thanks for the help guys.
I'm suffering the same thing! I just went out to drive my car (been a week), and I kept having this feeling like I was sitting too high in the seat and rubbing the roof. Turns out I have a huge blister (?) of my headliner sagging down. It won't hold back up in place either when I try to smooth it back into shape. I saw another blister forming in the middle of the headliner.
My interior is so mint (was!) and now the dreaded headliner sag. Seems from doing a search it is quite the common problem. And, (gasp!) I hate doing interior/upholstery work. I always break those damn hidden clips........
Oh well, guess it's time to learn a new repair.........

Go to Thirdgen Resource's website and click on the Tech section. They have a page on doing a headliner swap that should answer all your questions. Doing a headliner swap is a 30min-1hr job. As for recovering the one you have it takes about 3 hours. Believe me,it's not difficult.
Glad to help. Your's is the blue Formula in GMHTP some time back isn't it? How's the car? Last time I visited your website you were putting the finishing touches on a 5 speed swap. How did it turn out?
Hey Mongoose! I just pulled down my headliner. Thanks for pointing me to Thirdgen Resources tech article it helped alot! 
My 5 speed swap went very smoothly, and worked flawlessly for 200 miles. Then I started blowing slave cylinders. Turns out I needed a long t/o bearing. I made a longer clutch rod (same result) and it has been flawless and perfect for over a year now.
