The door trim is fixed to the door by two means:
1. 'bolts' (torx type screws, of which you found two, but there are 3)
2. 'clips' or 'studs', around the outer edges (6 or so)
The screws can be found near the handle (and then I mean where you grab the door, not the metal thing to actually open the door). Take care not to lose them to the innards of the trim when you taken them out. You found those already.
The third screw can be found behind the grille of the tweeter (in front of the door opener handle). Pry off the grille with a flat screwdriver and it flies right off.
Then you need to unclip the studs on the outer edges. There is a small semi-circular hole at the bottom of the trim, in the middle of the door. Start by pulling there, straight out from the door.
The first time it will take quite a bit of effort and also make a lot of noise. Don't worry too much, it will stay in one piece. Unless you start ripping like BamBam
There were some pictures on this forum of the approximate positions of the studs. I've kept a bookmark to this page:

See the first picture.
Anyway, after unclipping the studs you can remove the trim by sliding it upwards a bit (it hooks behind the door where it meets the glass, at the top) and then away from the door. Speaks for itself.
Although you probably won't need it, you can unhook the lock-release cable and some other electrical cabling to reallt move the trim far away from the door. But if you only need to unhook the mirror trim, I'd keep it fixed (especially the driver's side, where I couldn't unhook the electrical bit easily. Passenger side is easy though).
BTW, also make sure that the studs are still in one piece after pulling them. Sometimes half of it stays in the door. They should be repositioned for refitting. After doing this about 6 times myself, I never had a broken one, so don't worry.
Hope that helps.
And o, welcome to the forum!
