I would think you would be able to keep some of the less light demanding SPS species on the bottom of the tank. As for bulbs and fixtures Loyalrogue just posted a group buy on the Sunhlight supply stuff. Check out there website to find the various sizes. I would go with whatever fixture would fit over the tank with the most bulbs.
at least 4 36" bulbs with quality reflectors. Are you doing retrofit or a fixture? If a fixture, I would strongly suggest Tek, if doing retrofit, I would suggest the IceCap SLR reflectors or a IceCap retrofit kit.
