I've looked at it in LW now. There are no unwelded points and the UV looks fine. I think the problem occur in Poser when you set up the groups. To avoid that: 1. Set up the groups in Lightwave instead (it's called "parts" in LW) before you export it to OBJ. 2. About the UV. In Lightwave, before you export to OBJ you will need to assign the UV-map to a surface (F5 to bring up the surface-editor), no need to select any image, just the UV.
