10-12psi on a good tune, you can get by using an oem clutch, but id suggest something that can take the punishment that way it doesnt become a problem in the future. As for flywheels, stock is fine, just get it resurfaced while it is out of the car.

aem fuel rail isnt necessary, if you dont already have it, dont bother getting it.

edit: forgot to factor in FMU, if you are using an FMU... I would not go over 8psi. Pick up an uberdata kit and use that.
