Sc-trim, what else do i need.

I will soon be purchasing the sc-trim and was wondering what i will need to complete my car. I will be running stock cam, gt-40p heads, and a edelbrock performer intake. Unless i can find a really good deal on mass air and injectors i will most likely be running the stock 19's with the fmu. I have heard that with 19's the 12 : 1 setting is way rich and you can get away with running the 8:1 on the fmu, is this true? I currently have a 190 hp holley fuel pump but am trying to sell to get the the walbro high pressure 255 or whatever it is. so my question is...
1 - what spark plugs should i run?
2 - what pcv do i need?
3 - do i need a bypass vavle while only running between 4 and 7 psi?
4 - do i need to upgrade my ignition with only 5psi?
5 - Can i just simply bolt it on and go? i plan to get a dyno tune
6 - also i have a brand new timing chain and lifters, should i install those or just send them back for the extra cash to get a power pipe or different pulley?
let me know what your opinion is. thanks

The SC is a plug and play..U don't need anything else, unless u have visions of a "AA Fueler"..If u decide 2 up the boost, then thats the time 4 other stuff.Otherwise it's absolutely unnecessary & waste of $$$$ also might give u some drivability probs...

anyone else able to answer all my questions?
