To replace the head liner you have to remove the sun visor's they have screw's holding them on. Also the grab handle's to help you get in and out have screws holding them in you just have pop the cover over to the side to get to the screws on the front handle and the back handles you need grab the screw cover by the handle and it hinge's away from the handle and you will see the screw's. The dome light has to come down if you grab the the dome light where the switch is and push it towards the other side of the dome light it will release and come down. As far as the a and b pillar molding's the front one's they have metal push pin's that you take a flat bladed screwdriver put it under where the clip is and pop it loose. It's pretty easy to replace the headliner's.
