My 2 cents:

Might want to uncomment the following line in your named.conf

        // query-source address * port 53;

This will revert to the pre BIND 8.1 behaviour. If you PIX rules are
setup that way you probably do not get the delay anymore.

Regarding the saturated link: try the eliminate method: stop squid for
a moment (yes users will complain) and do some DNS testing and see if
anything changes. If DNS responds normally take a look at the squid
config. I setup my squid with delay pools to take 80% of our bandwith
so some is left for other stuff on the link.

Marco.
