ideas and suggestions

I've got some questions about the rig I'm planning to use as LD of a small budget musical. It will be performed in a community hall. The stage is about 6x7x5, raised 1m off the ground, and the two FOH lighting bars angled into the stage are on the ceiling and about 5m out, one on prompt and one on O/P. I can't use our pushup stands as they don't achieve enough angle to stop washing out the cyc.

1. Would a pattern 23 be of considerably less intensity than an acclaim 650w PC? And would using 2 PC's across the front of stage at a 5m throw illuminate adequately? (I have no central FOH rigging position so I'll split the stage in two, and using 4 PC's across FOH will increase costs since I have two major lighting states gelled up differently).

2. I have to use 4 pairs of 110v par 64's somewhere as we are at a premium with lights to hire. I'm thinking of using them (at 50%) above stage as a general wash, however I'll need to diffuse them. How can I control the spill though? I'd rather use them on-stage rather than FOH since the spill looks worse when seen all over the proscenium rather than all over the stage.

Any opinions, suggestions?

Thanks,
