I'm using Girodisc 2-piece STI sized rotors. They are dual drilled to work on 04-07 STI's.

Let me see if I can answer all of your questions:
If you have an 02-05 WRX you'll need either the adapter brackets or 06-07 WRX backing plates.
You would use an 04 STI sized rear rotor, as that is 5x100 and the correct rotor size.
06-07 wrx rotors are too small in thickness and diameter for STI Brembo calipers.
The STI ebrake shoe with NOT fit any year WRX backing plates (the hub/bearing is much larger), so no, that would not work.
