1)IMO your gonna need a FMU if you wanna use 30lb injectors on your car. I'd actully sell them and upgrade to a set of 42lb injectors and ditch the FMU.
Kirban is the only way to fly when it comes to fuel pressure regulators. They're a nice high quality billet peice. Mustangwarehouse.com has them on sale for $67.99.

2)I'm not sure on the timing. A dyno tune is your friend.
3)Yes that intake is too big. Put it on a shelf in your shop till you've got aftermarket heads and cam. Or sell it and recop some of your money and put it towards a milder intake.
