I really recommend against working with a morphed figure to save poses from, if you ever plan to distribute those poses.  For one thing, some "morphs" are actually scaling bones (e.g. hands size, shoulders size in V4) and will make poses that do not work the same way vs. the normal character.  Bends will be to the same degree, but since the bones are of different lengths, results will be different.  If you're only ever going to use those poses with that particular morphed character, that's OK.

Quote - Then, under each actor, it said rHand, rThumb1 etc, even though I had selected "left".

This is the difference between Internal Names for things, which is all Poser cares about, but never shows you; and the friendly name, which it never actually uses for anything but to show you in place of the real Internal Name.

Poser 7 and onwards also includes some junk for "Universal Poses" including thighLength, targetFigure and refFigure.  If you're redistributing, best take these out.  Also for every actor, you probably see channel information for "translateX" "translateY" "translateZ".  It is safest to delete these also, even if you think they're all zero - what if a user doesn't WANT them to be zero?  At best, you want them to do nothing, and if you delete them from the pose file then they'll do nothing.
