You can get away with >50W/Sq' if you use T-5's.
Thanks for the feedback.

Got plenty of fans, so I'm not worried too much about ventilation. I'm heavily weighing the options, but Opie and MVP are right about the HID being overkill... fluoros will give off much less heat, and I've got quite a few CFLs and socket extenders laying around. I'm gonna go pick up a T-5 setup later this afternoon, too.
