Well I can't answer all your questions, but I'll do what I can.
You'd probably pick up a few hp with a 70mm throttle body.
I'd get a 73mm Pro-M mass-air
Yes Cobra, springs will fit on a GT
Yes high-flow cat's quitein the the car down. And yes you will lose some ET
A set of 24lb/hr injectors would be nice
