sunpowers are the bomb - 4 bulb is fine - coral placement will optimize the smaller light. So SPS directly under the light, and low light stuff closer to the glass. You dont want a ALL HIGH light tank or you wont be able to grow other corals.
get a BRS reactor - it mounts outside of the sump and all that sits in your sump is the mj1200 pump that powers it. You can put the mj1200 in the frag tank if you want so the carbon filtration step occurs once the water cycles through the frag tank.
as for bulb combo - depends on what you want. Are u looking to setup a true frag tank (ie. optimize growth above all else) or do you want it as a "display frag tank"? If its the first than all you want is high par bulbs, if the latter, than you want to mix up the bulbs a bit to get some good colors.
