You will need the sti wire harness because the sti is drive by wire. I've heard its very difficult to swap.

Not only the wiring harness, if I recall since one is drive by cable and one drive by wire you need to change pedals also. Im not sure about the transmissioni.

Putting an STi bottom end on WRX heads is a much more desirable choice, it makes the swap easier. Search hybrid block on here. You could continue to run your 5 speed either way, you just need a WRX clutch between them.

You can't drop an 07 sti motor into a wrx with a ton of work. Harnesses, pedals, ecu, are just a few of the things needed. I think you have swap the motor harness and the body harness to get the STI ECU to work.
Buy the STI motor, sell the heads, get wrx heads. This would make life a lot easier.

No.
It might work if you swap out the intake manifold and TB from the 05.
