pinstripes- I let my car is toutside in the sun for an hour or so then pulled it into the garage. The pin striping comes off by just peeling it away, youll need a little patience. There will be a nasty residue underneath the pinstriping. Then i took an old totoh brush and used Bug and Tar remover and went to work scrubbing. Little by little it will come off, its kind of a pain in the ass but my end result is CLEAN, ill post a pic of my side at the end.
For the badges some of them are mounted in little holes in your trunk. I believe the LE for you will have 2 holes (1 per letter) and the toyota on the left will haev one. Use a hair dryer to heat them up and once its hot, not scorching, use dental floss to get in between the badging and your trunk. as far as getting them back on, you have to make sure your trunk has all the residue off where they were before, and the lettering has to be clear of residue as well, or else whatever you use wont stick. Im not sure what your best bet would be there.
For your turn signal light you kind of have you glide it out of a bracket, once it is out youll see that theres a little curve that latches it into place. It takes some jiggling but once its out its easy.
