Removing Headliner?
To remove the A-Pillars, there's two screws at the top of the A-pillar where the t-tops fit in, and then two metal clips that slide into the metal of the car, so you have to kinda slide it towards the center of the car while pulling up gently. Don't do it too hard, or else you'll rip the metal clips right off.
You'll then have to remove the sunvisors, three screws, easy enough.
For the rear portion, you'll have to remove the panel where the speakers are. It's MOSTLY held on by velcro, but you'll have to unscrew the kicker panel next to the front seats that runs along the bottom by the floor. Once you remove the rear screw of the kick panel, you can get the bottom of the panel out from behind it. Then your fun will be with the coathanger that's in the top center of the panel. It has a square tab in the center, the more you pull the tab out, the more the anchor will collapse and allow the hanger to pull out. Truthfully, I hate that thing, I just grab the longest flatblade screwdriver I can find and just pry it right out. It's not easy, and it's not fun lol. Once that's out, pop out the plastic cover that goes around the seatbelt at the top, then you'll see the opening in the panel where you can guide the seatbelt through it. There's also two "caps" on the top of those rear big panels, two screws removes them and then if memory serves correct you just have to tug on the panel a bit, it's mostly held on by velcro tabs. By that point, I think it's fairly easy to get the headliner out.
