You could probably go with a couple in-line connectors for the switch, although a terminal would be more tidy.
I really like posi-locks for my wiring needs.

Since the last 2 pairs of 55w lights (so 4 total) = 220w total, I probably only need one more 30amp relay instead of 2 relays & then I can just splice the 2 relays to the dash switch. Correct me if I'm wrong...

220w / 12v = 18.3amps so a 30amp relay should be fine
