I have complete testing of our squid implementation...here is the Cisco information for the wiki. Unless someone objects, Iwould like to submit a detailed howto to squid-cache.org for CentOS 5.1 deployment. This solution is working VERY well. Special thanks to all of those on this list who gave some of their time and knowledge to helping me out.
