Quote - I think I've got a handle on making it a conforming figure, it's fusing separate props into a single piece that I'm stuck on. Is this even possible to do within Poser? (I've for Poser Pro 2010).

Yes, it's possible. All you need to do is export the props to a single OBJ, pick the items you want in the file by using the Subset option.
It would be a good idea to use the Grouping tool to assign appropriate groups and mateials before exporting, and therefore be sure to tick the right options in the export dialog.

DrGeep has tutorials covering the steps if you want an illustrated guide.
