Which MSD part do I need and part #'s

Need help with which MSD ignition components to purchase with part numbers. I have the MSD 6AL part # 6420. I want to launch my 88 fox turbo 5-speed with some consistency so shouldn't I get a 2 step launch control? Is that part number 8739 or 8734? I think it's 8739. I need a coil, what part number and I need a distributor. Pro Billet? Which one do you recommend and what is the part number? Any good race shops to get all of this stuff at?

Thanks,

Thanks! I will start with those numbers and get after it.
