Need Lighting Advice for live music/dance shoot!

I'm preparing to shoot a live music and dance performance which will feature appx. 4 percussionists (congas), 4 singers, and 2 dancers. we'll be shooting in a rehearsal studio 30ft wide by 60ft deep. We're shooting with 3 JVC 5000 dv cameras and a protools setup to record audio. The musicians and singers will be setup in a shallow semi circle with the dancers moving out in front for a portion of each song. Can anyone suggest a practical plan of attack on the lighting? We're working on a tight budget and I do not have lighting experience. We should have access to the following.

2 or 3 keys = 1000 watt Fresnel
Fill = 500w Soft Box
Back Light = 500w Fresnel
Back Wall = 500 Fresnel

please advise. are we going to need more than this?

thanks,
