FiTech EFI system

I've got the money to make a jump on a Fitech in June, but I have some questions before I make the leap. This is what I got or am planning on getting. I even have a friend who is willing to give me a helping hand.

Engine:
408 Stroker with Forged internals. Camshaft is a custom hydraulic roller with either a 238/242 or a 242/246 (cam specs were lost). Milodon road race pan. Engine Quest heads ported by IMM. Edelbrock LD4B intake that's port matched to the Engine Quest heads. 1-inch carb spacer. MSD Ready-to-Run Distributor. 34 degrees of total timing. Not sure how much vacuum but I don't think it's much because I couldn't run the vacuum advance on my MSD distributor. Engine made 523 hp and 522 ft-lbs of torque on the engine dyno.

My first question is, for a Fitech Fuel Injection system, should I switch out my LD4B for my Mopar M1 single plane intake? I will mostly be doing street/highway cruising but will autocross and road race the car. I know single plane intakes, generally, is meant for higher rpm operations, but I've heard of some people having trouble with the TBI fuel injections and dual plane intakes. Can the LD4B be a little too restrictive for my engine and do you think my 408 stroker would be more happy/forgiving with the M1 intake? A Fitech Rep told me that if I'm running 5-6" of vacuum I may need a laptop tune and that a single plane intake "may be more forgiving." I may be able to run the 1" spacer with the M1 intake.

My next set of questions is with regards to the parts I was planning on purchasing:
Fitech MeanStreet (800HP)
Tanks Inc EFI Tank
JakeFab Fuel Puck
Aeromotive 11540 In-Tank Fuel Pump (340gph)
Tanks Inc Sending Unit

Am I missing any other parts I need to get? What do you guys recommend for fuel lines?
