all you really need is a phillips screw driver, and a flat head scredriver.
the round plastic clips that have another round thing in the middle, just push the little round bit in, and the wedge the whole thing out. a bit hard to explain.
all the clips are replaceable, so dont worry to much
most of the trim such as the pillar covers and door sills, and other stuff like that just pull off. The door panels are attached by screws on the bottom and clips on both sides, and after removing those you just pull up on the panel to get it off.
