Nope... there's no need for an FMU if you have the afc.

I dunno... Around 10 psi or so if it's properly tuned should be fine.

No check valves and if it's tuned well 12 psi should be fine.

What's all this talk about boots? :P You don't use check valves/missing link with the AFC. How high in "boost"? How high do you want to go? The AFC can handle more than your motor can. If you're running stock internals on a daily driver, I wouldn't go much past 12psi, depending on the turbo.

I would get some good fuel management if I was boosting 20 psi on a built motor.
