I'm not gonna sit here wondering what colour her corset is because I already noticed that two are 'sheer' - and that's fun enough for any man :-P

I think that is key, that's pretty much the way I see it, I'm sort of between what Vilters and Bantha prefer and what you just mentoned.  My own decision would depend on how transmapped resources work (and I'm unsure about that).  For example, if putting the textures for parts that require transmapping all onto one texture, would be a resource hog, then I'd put all continuously connected stuff onto one texture, and all the discontinuous transmapped stuff onto a smaller one.

The only thing I would never do, not in a million years, is put different parts of what is supposed to be a continuous surface, onto different maps - it just seems ridiculous and like Vilters said, totally unnecessary - it's been the biggest most pointless pain in the arse ever since I started using Poser.  Just my opinion, but I think all skin should be on one UV and texture map.  I personally have no problem with eyes and fingernalis being on a different map because they're not supposed to be part of a continuous surface like the skin is anyway, therefore painting those would not cause any problems with edges, them being discontinuous from the skin in real life anyway.

It just seems the logical, sensible way to do it.
