If anyone interested finds this: I couldn't find anyone who had done this and wrote about it. I'm still figuring it out, after a lot of dead ends, but I do have my first working figure. After trying methods using 3d studio, blender(multiple versions since scripts seem to work only for the version they where written for- and Norton's hates blender.exe) , hexagon and a few others and addons I got it to work with Just XPS and Daz (with blender as a little optional help!). The Kasumi DOA figure rendered in my Gallery (as of this writing) was rigging automatically with the G2F skeleton (cleaning up the joints is on the "to do" list) using the DAZ built in transfer tool. The basic steps are:
(note: I did play with export and import scales but I didn't keep track, and mostly they didn't seem to matter, you can resize after too.)
1) Export a copy of the DAZ figure (in my case G2F) whose rigging you want to use, with a zeroed (default) pose as an OBJ (The pose is IMPORTANT.) I also had to rip out all the textures to get this to work, and replace them with a blank texture (a 50x50 solid square created in gimp.) Its the NEUTRAL POSE that matters.
2) Import the Daz obj into XPS. Open the figure you want to send to Daz (DOA Kasumi, in my case.) Scale the figures as close as you can get them, and then pose the XPS figure (Kasumi) as close as you can get to the the DAZ neutral pose. Even though you can edit the rigging in Daz, the closer the pose, the better the initial pass at the rigging will be, I'm sure there are people somewhere that actually enjoy rigging, but that ain't me. For these images I didn't even open the joint editor. (Besides I'm sick of joint editors after hours with DAZ's, and blenders, and 3d studios that didn't achieve much other than a headache.) The simpler the pose dials the better, as the skin does distort, try not to twist it.
3) Export the posed XPS figure (Kasumi) as an obj with textures.

3a)Optional- if you jump right back to daz the materials don't follow the obj, the zones do so you could fiddle with the textures (which will have more or less logical names I suppose depending on who has worked on the model so far.) The option is to import the obj into blender(or perhaps some other modeling program - I just know blender worked!) and then export it again as an obj, right in the same place as you imported it from, (overwriting the figure you exported from XPS.) This will magically launder the obj so the textures carry through into daz. I've read you can smooth the model and delete duplicates at this stage too, but I can't figure out why these options are sometimes available to me, and sometimes they are not. I know people love blender - but I DO NOT find its interface intuitive.

4) Back to DAZ, load a new scene and a new copy of your spine donor (G2F.)
5) Import the XPS figure (Kasumi.) The only options I changed was the axis order to make it X,Y,Z (but yours may already be at that) and I used trial and error on the scale to match the Donor figure as close as possible(not sure if it is necessary, but it made me feel good )
6) Run Daz transfer util (edit-figure-transfer utility) Source is G2F , target is XPS OBJ. I used the "fullbody" template, but it doesn't seem to matter much, it worked for me as gloves (hoping for better finger bones) and as blank. Under advance turn off "fit to" after completion.
7) That should do it! You should have a full (and reasonably accurate) rig for your character. Try out a daz pose on it!
I hope I didn't miss anything - this is from memory, and there was a lot of trial and error.
Also: I got the hair transparencies to work with out any graphic editing. This might only work when rendered in octane, but for the transparencies (hair, eyelashes and eyes):
1) Load the default color texture for that object as the transparency map (down triangle on the line with "Opacity Strength" on the surfaces tab.)
2) Click the down down triangle on the line with "Opacity Strength" and choose "Layered Image Editor.
3) Create a new black layer, and position it under (after) the base one on the list.
4) Click on the original layer and then check "Invert (Negate)"
5) Apply!
Good Luck!!!!
