For the UV re-mapping:

This will be a waste of time for most newer Poser figures, as the "pelt mapping" is already the most effective mapping possible that gives the least distortion with the best use of UV-space.

A simple "front-back" mapping like the old Poser figures had might appear simpler to paint on but will give you very nasty texture stretching and if you're not really careful you might even create overlapping UV's, making the figure unusable.

Get yourself a 3D-painting program that lets you paint/texture directly on the figure instead of messing with UV-seams.
