for lights, I would use a 65watt lights of america fixture from HD,
If you can connect the sump and 'fuge w/the bulkhead that would be good. you could supply the 'fuge with water by diverting water from the return from the S.O.S. and regulate it w/a gate valve and have everything go back to tank via your main return pump. Hope this all makes sense and helps.
