What to do first on my 4G?

[white_4gGT]

Ok, my 4G GT Auto (08) is still completely stock.

As usual, there are budget limits on what I can do this year. $1500 is my limit at this time.

What would you do?

Coilovers ($895) - seems like a deal
Intake (???)
Exhaust (???)
front strut tower bar
rear lower bar

Thanks for any input.
