QFT, i just got my car back from the body shop after being rear ended. Make sure you hold your ground and know your story. The insurance company will try to pressure you into excepting less. get EVERYTHING fixed like it was before (or better if you can get away with it) They tried to make me pay $190 to paint my spoiler, because it wasnt damaged in the wreck. I told them that it wouldnt match the new trunk paint, but they didnt care. In the end, i only paid $21.02
and again, if you can get your hands on some stock tails from a totaled 350, do it. It will cover all your bases, if nothing else.
If i can be of any more help, let me know. I JUST came out of the situation your going into, so i feel ya.
