David, that camera sounds very very cool. I'd love to be able to focus my 35mm Widelux, but the bits and pieces are pretty tiny, you'd need tweezers. I'm jealous of that big negative - that should really rock.
About the only suggestions I'd make to you then would be to pose your group along an arc that's one of the focus distances, to have subjects as clear as can be. And you have shift on that model Noblex too, correct? If so, you can keep the camera level and just shift the lens down a little to keep the feet up a bit from the bottom of the frame.
Have fun, post up when you have something neat to show for your efforts. It won't be long, is my bet.
