Great car, got any pics?
As for the side marker the following should work...
Unscrew the single mounting screw with a #1 or #2 phillips head (the one in your trunk mounted tool kit will work fine).
Gently pry from the back (end closest to your door handle). There is a retainer clip on the other end (closest to the front tire).
Once loosened, just pull the assembly out and replace.
Reinstall in reverse.
(There is a very slight chance the retainer clip is on the other end, it's been a while since I did this)
