Autolite or AC Delco will work just fine. Personally I'd put the AC Delco R44TS in and go for it.
As for Wires, they're all pretty much the same. I like Prestolite, MSD, Taylor and Bosch.
You can also get AC Delco wires, they go for like $35 for a set.
While you're at it, get a new coil.. what the heck.
