Making Portal 2 weapons within 3ds max and some more questions.

[huyu]

Okay, so what happened was I decided to make a mod for portal 2 where you would utilize the "old" version of the aperture science HPD: [media]http://tdoyle.me/s/SS-2011-04-22_01.30.46.png[/media]
I still got work to do on it, but before I mess it up I have some questions.

So what I want to model is a backpack with an attached "hose" and attached to that is the portalgun, which looks more like the end of a fire hose.
Can I make bones for the hose?
Can I attach both the backpack to Chells back and the gun to her arm?
Any good tutorials on the making of both w_ models and v_models?

Thanks in advance!
