Welcome aboard, man... Slow up, get some punctuation in those posts... it'll be way easier for people to read (especially the people who have the answers you're looking for).
If you've got the $6k to spend, I'd take some time and make sure everything is going to 'play nice' together.
I'm sure someone will pop in who's better-equipped to comment on the turbo choice (for replacing your OEM ones).
I think I'd start off with the maintenance items (TB change, water pump, etc) and make sure everything is perfect before bumping up the boost. You already know that every lb of boost increases the likelihood that something weak will go bad. Maybe even find a set of upgraded OEM turbos for the time being, while you decide on cosmetics, SMIC, and exhaust configurations...
There's a reason a lot of Z32TT projects start off awesome, and get parted out.
BTW< I edited your title. "Mod help" looks like you need your password changed or something.
