I opened the helmet1.obj in both UVMapper and a text editor. Your group names are "head object_1" to "head object_16". I don't know how Rhino displays the groups and it may be that is what is causing the confusion. It should all be in one single group called "head".

When you import it into Poser try panning back. It imports into mine but in a position 6 feet in front of Dork's feet.

Hang in there bud you will make it :)
