If Wings is like Silo then you should do fine.  I use Silo and get some nice results.

As to the magic shrink button, you can use the Poser Cloth room to do that to some extent.  Once you have your basic mesh, I find that taking it into the cloth room for a little drape or shrink wrap can work wonders :)
