I've done the headliner replacement on both of my Crossfire coupes. Both times I removed the headliner, and had an upholstery shop actually do the removing of the old fabric and glue, and gluing of the new fabric to it. I then did the reinstall of the headliner myself. The first time the upholster cost was $150, and the second time $125. Most will also do the removal from the car if need be. Do a forum search and you will find more information on the headliner replacement cost. If you want them to remove and install it in the car that will cost more, as well as for an exact fabric match. I decided to pick a look alike they had in stock.

BTW, I also own a SE convertible. I found with the SE the cloth seats are way more comfortable for me
