Free Poser format exporter will save regular poses and morph poses, PoseWorks Mat file script will write basic (Poser 4/propack plus displacement if used) surface information, all of which can be sued to rebuild the scene. Lights and cameras can't be exported, and of course Poser won't let you apply any poses to unparented props (but you could, if positioning is important, export those as OBJ files using the Poser preset since they don't have any joint information to lose). edit: there's a sticky in the D|S Freepozitory on the DAZ forums with links to those scripts.
