Does poser come with lower res meshes that you can use in realtime apps? The model you've got there looks like the sort of thing you'd use to make normal maps, not the actual realtime mesh. I hate to ask greg, you know whats coming... but whats the triangle count? looks like you've got a couple of thousand in each boot!
The suits are called mechanical counter pressure suits btw, if you look it up you might find some good ideas for detailing and texturing, like the inside of knee, elbow and shoulder joints are specially designed so they don't produce any creases that the body would swell into, you could reflect this in your modelling and textures (better off in textures and save your polys though man!) those visible creases in the mesh for example should probably be eliminated - she'd probably get a nasty welt or something between her breasts in real life, not good for such a fine figure.
