Only ever load the eq2ui.xml or you'll break dependencies. And the graphic window is always empty until you select a tab (and if necessary toggle individual windows visible via the eye icon on the left).
Copying the paperdoll is trivial, simply find the <paperdoll> element in the inventory, copy it and paste it into your window. Then you'll go through a lot of trial and error getting it to a size and placement where only the head shows (you may need to adjust its vertical position via script for the smaller races). have fun!
