Topgunz - air to air upgrade

Z Warrior

08 g37 coupe 5AT RWD

I'm thinking about doing this and buying the parts slowly and installing when spring arrives next year.
I have FI catback/rhfc (I'll change the rhfc for test pipes down the road)
Since I have an 08 I can only use uprev correct? It will be my daily until I can buy a beater down the road. I'm aiming for 420-450whp (nothing crazy yet...) I don't see myself using E85. Do I need the 9lb pulley?

Do I need the transgo kit upgrade?

My shopping list so far:
Stillen SC kit
Topgunz A2A upgrade
TBatt idler pulley
SI trim upgrade from vortech
Tial QRJ upgrade
Injector Dynamics ID1000 (over kill or am i good?)

What fuel pump upgrade should I do? Is AEM 320 LPH E85 Fuel Pump good?
Which engine/transmission cooler do I need?
So I cannot use the oem crashbar correct? where do I get one that I can use?
What else am i missing?
