Anyone want to make a newbie make some good power?

Yes, the FP Green and the FP4Rs are both going to be gotten at a 5 to 10% discount, I feel they are as good as any to run for what I Want so I'm going with them since they'll be a little cheaper. As for power goals I'm not concerned with the numbers, i want it be to reliable. Shane told me my setup will make in the 475 to 500 wheel horse (corrected??) on e85 at around 30psi.
I forgot to mention the car already has a full 3 in exhaust, intake, upper and lower intercooler pipes, greddy bov, a wally 255, exedy clutch, and an AEM TRUBoost, among a few other misc. goodies.

so with that being said, can you guys provide some insight on why you would skip certain parts or what will/will not be needed? I don't want to penny pinch but spending top dollar on un necessary parts is also not wanted.

Thanks for the quick responses guys, and thanks for being so accepting of my Newb-iness!!
