The DE(hqi) lamps put out more PAR generally, but require UV shields. They also require electronic ballsts. Both types are readily available in 250w.

Yes. I'm not sure exactly how deep a 72 bow front is, but 250w SE(moguls) are good in tanks up to 24" deep. Acro's should do fine at mid level (maybe even lower) to high in your tank. Here is a great site for comparing 250w SE lamp/ballast performance along w/ some pictures to show the color difference between manufacturers and K- http://www.cnidarianreef.com/lamps.cfm

You could do sps with that lighting. If you can afford it though I would consider going HQI, but HQ(mogul based) would do fine. I would go with 10k MH with plenty of actinics.
