Ports

[SeaJay]

The Symantec Security site says port 2000 is open on my router.
The grc.com (Shields Up) says port 53 is open on my router.

Should I be concerned?

I don't see anything fishy when running nestat commands with various switches (-ab, -n, etc).

You're probably fine. Read here: http://www.eggheadcafe.com/forumarchives/windowsnetworkingfirewall/Nov2005/post24250779.asp
If the port is also listed as Stealth, I wouldn't worry about it.
I have several ports open, due to using torrents, for instance.
