Get a spray addhesive that is high temperature from places like michaels, which also has the foamy headliner fabric. The job is not very complicated: Make sure you unscrew all handles, visors, pop out the lights. Take it out from your trunk and scrape all areas, be careful because getting old flaky headliner material on your eye is bad. The spray can was around 20 dollars and the fabric around 60? Sorry I did this like 4 years ago. I would say go for it. One thing i wanted to do tho was to glue some crazy pattern on my interior roof. If you go that route, please post a pic!
