I don't know much about Poser Physics, but if any of the objects are still touching, Poser Physics will force them apart, I know that much.

As for doing it in Poser Pro 2010, that is my quest, too.  I will have to write to the Smith Micro people to find out if there is a version that will work in Pro 2010, and then decide if I'm willing to spend another $50 to buy it.  Everything I've heard indicates that there is no upgrade path for items bought from the old Content Paradise store, and that's where I bought mine, of course.  [bitter smile]

I'll report back here if I learn anything.
