Welcome to SHO
I would first check the sticky threads at the top of the forum, for information, use the SEARCH tool up on the toolbar, and check the Performance Tech forums for additional information before asking such a huge and rather ambigious question. The honest answer is until you know more about what you want your car to end up like, its hard for anyone to give you reasonable advice on what to do first...
Gratz on your new Acura though, post some pics of it...
