Thanks for the tutorial (and for giving ockham and me credit). For creating outlines, you can use Photoshop (or similar) to extract outlines from a Z-buffer or normal image with an edge detection filter. You can get a Z-buffer image using the depth cue mode or you can get colored normals with special Poser 5 materials. Depending on the filter you use, you can get outlines with varying thickness. I attached the link to my toon shading mini-tutorial, you should be able to use the outlining part with z-toons as well.
