Not quite sure which stage of the setup your at,

if you're rigging then you have a couple of options - the set up room or using a Hier File (A Heir File is the old way of setting up figures but is useful for things like tails, buildings etc - you set up a text file with the rigging and use that instead of the setup room - See page 1061 of the Poser Reference Manual )

if you've already rigged then something like 3dcheapskate Freazypose will help - download link http://www.sharecg.com/v/90793/gallery/8/Script/Freazypose-prototype-0.10
