Looks good to me! You may be pushing it with some of the more light-demanding animals, like clams and anemones, but you'll be good with everything else.
I have a 4' 35 watt or so metal halide and a 2' 65 watt florescent on my 5' tank. It's kind of lame... But of course I'm not keeping and photosynthesizers.
For my 240, (which was 7 feet long), I had a 6 foot light. That left 6" of space on either side, just like yours will have if you use that light. I did what Hannah said and just kept softies on the sides. They are fine with the lower light levels.
