You are not, with respect, anywhere close to being ready for "tuning." Begin by getting a good intake, either CAI or SRI. Just about any major brand spoken well of on the boards. Drive with it for a while and get used to it and make sure you are not getting any check engine lights. Get a boost gauge, or better yet, a scan tool with data logging, like Dash Hawk. Do not replace the BPV. Stick with stock for now and perhaps permanently. Consider adding a rear motor mount, although the stock one worked for me for a long time.
Mods should build on each other in a compatible manner. Make one change at a time. Otherwise, when you encounter an issue, and everyone does at some point, you will not know what went wrong or why.
Tuning options come much later.
You need to learn how you car is performing and know what to look for before you start thinking about "tuning" unless, of course, you want to join the zoom, zoom, boom club with a rod lauched into orbit.
Slow down. Take it in steps. Your engine will thank you.
