Not sure if I have the term right, but what you are describing for the most part concerns particle physics rather than bullet physics. Here are some resources for bullet physics and perhaps they can answer your questions better than I can.

Poser: Bullet Physics Webinar

Jay Versluis's "Getting Started with Bullet Physics in Poser"

And to better understand the open source of Bullet Physics: Bullet Physics.org

Hope this helps. Sorry I couldn't go down your checklist. But this will help you understand what it can and cannot do.

Cheers!
