1. You're the best person to evaluate if ns is best for your purpose.
I suggest you look at the documentation (at
<http://www-mash.cs.berkeley.edu/ns/ns.html>) and sample scripts (in
the current release).

Ns could be used to simulate VPNs, but you could have to add a little
or a lot of code depending on what your research questions are.

2. See the Greis tutorial (in the documentation off the above web
page).

3. Some related work is listed... on the web page.
