Experiment with what you have and learn from it. put the floods paired up from the front or sides onto the band and use the effects from the rear as they will show up though the haze. depending on the current output of the dimmer channel and of course the connections you can add to the dimmer the 38's and so on. The non dmx lamps which usualy cannot be dimmed are best controled using a switch pack controled from your desk or a manual switch box if you are close to the lights and dont want to have then programed in. sounds like you could do with at least another four chan dimmer. Hope thats some help ??
good luck and enjoy!!
