For what I'm doing importing a Poser figure into Blender and then scaling my prop meshes in proportion to that has worked best.  Since I'm exporting several props, once I knew the scale settings it was a simple matter to repeat the process and export each one.  They imported fine and all at the correct scale I wanted (which actually turned out to be about 140% roughly of standard figure size), then all I had to do was make sure the origin points were all correct, edit the pp2 file so the geometry was external and they're working fine.

Thanks again for the tips.
