It really doesnt matter what turbo you use, you'll need a tune regardless. The different displacement motor as well as the different injectors mean it NEEDS to be tuned right from the start. The turbo doesn't matter as much.
If you have someone who knows RomRaider around then they should be able to at least set your injectors up and then do some logging to see if the car idles and cruises around light throttle, but I would only drive it to make sure everything is ok and then have it tuned.

#12 - I'm buying stock in Glad Plastic baggies.
I bought these divider trays from Lowes which were really helpful in the past. You drop your nuts/bolts into them with a piece of paper to label. The nice thing about this is things stay in order so you just go in backwards order to put it back together.
The baggies get a little unorganized but they work fine, I've used them as well.

Ahh, found a pic of the tray I used when I tore down my EJ207 (and then decided not to go with the EJ257 instead). One engine, 3 trays...

Yes the air pump is on the 07 STi (and the 06 WRX). I am not sure about 08+ models...
You dont have to remove it, but I did. It involved removing a plastic reservoir under the intake manifold as well as the pump. I had to leave the valve on the car and plugged in (but not routed to anything) because the MAP sensor wiring is related to this so when the air pump valve is unplugged the MAP sensor will not work.
And yes in my experience if you are able to find a complete STi motor that you can be confident in, it often is close enough to the cost of a hybrid that I prefer it. A new STi shortblock, full gasket/seal kit, plus labor to assemble it with your original WRX heads adds up really quick.

I don't believe there is really an easier or more difficult between the years. The only major difference is the 04 does not have the immobilizer so you dont have to make sure to have a matching ecu, immobilizer, and key.

Do you have the immobilizer code that goes with the ECU you want to use? I'm not sure how/if I could help out with this but I have a SSM III... but without the ecu and immobilizer all installed into a car to hook up to and flash I wouldn't be able to do much with it, so I dont know.
