Removing Headliner

[turtles_ride]

Just a question about removing the headliner. I recently purchased a flip down LCD unit that i want to put in where the overhead compartment is. I don't know where to start in getting the headliner down!!! My overhead light comes off easily as i've taken it down to change the bulbs to blue LEDs, and i'm just gonna rip the old overhead compartment off anyways to put in the LCD, but how does the freakin liner come off? Do the coat hooks have to come off, what about the interior moulding going up to the roof, do i just pull them straight off, or are there clips that i'll break? I'm gonna put new fabric on the roof as well while its down, (to match my door panels, armrest, steering wheel, glove box, sunvisors and passengers side airbag) its just thin stretchy material but i don't want it to sag, any ideas what kind of glue i should use? Any help would be great. thanx
