Yeah I would assume one pin is a ground for the reflector and the other two pairs are for each lamp in the fixture. What sorta ballast is required beats me though, I don't even see markings on the lamps themselves that would indicate a wattage. (He had a picture in another thread)
3 phase would have 3 hot wires and a ground. Would run 330v+. With 4 conductor wires and a ground, you would have a hot and neutral wire for a pair of 110v circuits.
More than likely. Always use a meter.
