You're naturally aspirated, right? Go with Autolite 25's gapped at .054, less than a dollar a plug at Wally World and they get the job done more than adaquately.
As far as wires, you've got some choices.
You know about the FMS wires, so I won't go over those.
I've run a set of Taylor wires, they were around $40. Nothing wrong with them performance wise, but I had trouble ripping the terminals off of them (yes, I used dielectric grease).
Now, I only use MSD Superconductors. They're pricey, above $80, but they're the absolute lowest ohm rated wires you can buy. Near 50 ohms as they're advertised. The terminals are double crimped to prevent pulling them off the wire, and the boots can be bent to taylor your needs. The boots are also beefy, so they're easy to grab. They're specific cut to fit the motor.
