I have had success with rope and tent stakes holding up the masts. If that is not an option, you might try 2ea 2x4's in a "+" shape. You'll need to secure the mast to the center of it, and run support lines to the mast from the ends of the 2x4's. As for the lighting, most hardward store sell 100W Flood lights in red, blue, green, yellow. Minions Web sells LED spot lights with a standard medium edison base.
