RE: trim?
if you take it off it will be warped but its kind of like a rubber material and while going back on it will fit perfect again, with civics i believe there are clips behind them, if i remember correctly, someone on her might have a diagram of which way they more easily come off but if not, just lightly pry with a clip puller or a screwdriver and after the first clip comes out look at it to see which was would come out the easiest for the rest, if you break any you should get some new ones or the trim will want to bend off the body.
