Quote - Hi,

I have one figure in my scene and using IBL.  In the preview I see the figure's shadow on the ground. What I would like to do is render that ground shadow so that it is placed on a separate layer when I export to PSD format.

The shadowy looking puddles you see in the PREVIEW are not actually shadows that have anything to do with lights you set up in your scene. To render those, you have to use an actual light that can create shadows. The best approximation for this would be an infinite light pointing down straight the y-axis. If you are using only IBL you should not get any shadows at all, at least not without AO, are you sure are getting shadows or is this only an effect from a nonuniform IBL-light? The only shadow you can get with IBL is Occlusion in which case you can proceed as Ms Nancy suggested.
