I have to say the anatomic detail in this is lovely ...but.

I think the level of detail you have in this base mesh is actually a bit too much.  It may cause significant issues in creating any kind of morphs for this figure as well as modeling clothing.  Its one thing for a direct sculptor like ZB, but remember ... the other vendors you hope will make additions for this may have nothing more complex than wings3d, hex and poser.

You might want to keep this as a 'standard' or 'muscular' morph and make a smoother mesh as the base - one that is easier to morph and to work over.  The easier a figure is to make addons for, the more used it will probably be.

As far as rigging goes - if you intend to use classic poser rigging, then you will find smoother is much less hellish.  The one you have now will need oodles of JCM's and mcm's to avoid ugly distortions.  If you don't mind the stupid programming thats one thing, but it gives me hives :P  There is a very good reason that v4 and now genesis are very smooth... its to make aftermarket additions easier, and to make changing the figure into other looks much easier. 

As for questions about walk designer and JCM's etc ... look for Nerd3d and ask him questions.  He should be able to give you an idea of what to look for and avoid when modeling as far as compatability goes.

and Hiya Gareeee!
