Check out the SANS Top 20 at http://www.sans.org/top20, in particular item
W9.  The list is one of the best resources around, and W9 addresses your
specific questions.  And that is a living document, so if any of the other
readers of this list have any suggestions or updates that you don't want to
post to the list, please feel free to email them to me directly.

Disclaimer: I am not a SANS employee, but have played one on TV.  Well, not
really, but I did do three of the sections in the 2003 Top 20, including W9.

Does anyone have an updated list of well known p2p ports?  

I'm also looking for any Snort rules to detect p2p activity.  Snort out of
the box comes with some rules for Gnutella, Kazaa, Napster and BitTorrent
but I want to be able to detect hosts running some of the more obscure p2p
clients as well (bearshare, grokster, etc.).  I have to imagine someone else
has done this already but I can't find the information anywhere.  Hopefully,
someone on this list has some resources.  Otherwise, I'll start reinventing
the wheel on Monday...
