The trim on the dash is extremely easy to remove from your car to be re-upholstered or swapped with a similar piece. However replacing the trim on your doors is a much more difficult task.
My LS came with the two tone black/gray cloth seats with matching gray dash/door trim. Here is it re-upholstered:
In order to remove each of the three pieces do the following:
Left of steering wheel/HUD:
Open your driver door, grasp the side of the trim piece, and pull straight back to disengage the clip(s).
Right of steering wheel/HUD:
Use a trim removing tool to remove the U-shaped trim around your stereo/head unit. Then grasp the right side of the trim piece[should be fairly easy as there is an open side to fit your fingers into] and pull it straight back to disengage clip(s).
Passenger:
Open your glove box and remove the two screws located at the top of the opening. Then pull the piece up and towards you to remove.
Watch my video for a better look at the screws needed to be removed:
