For lighting, I would suggest 2 radions length wise with wide angle lenses, with 2 t5's.
I diy'd a tek 8 bulb down to a 6 bulb with 2 multichips on a heatsink 8n the middle of them all. (Thread is here on RC somewhere) Dropped 4 of the t5 out after a month, and then the other 2 a few months later.
You may find that running the 2 t5's with the radions will be ok with your setup, but I preferred to turn all the T5's off in the end. Just as a note, I kept Nicks Purple Passion on the sandbed, along with Inferno nems and other light demanding livestock and everything did fine.
It also gives you flexibility on the outskirts of the tank for corals that don't need tons of light.
I'll find a picture of my 150 before I took it down and stored it.
