I go to http://localhost/ and attempt to connect to cachemgr.cgi and I get:

Cache Manager Error connect 127.0.0.1:3128: (61) Connection refused
Generated Tue, 08 May 2012 01:06:31 GMT, by
cachemgr.cgi/3.1.9@admins-macbook-pro.local

any help would be great.

Running 10.7.x with a homebrew port of Squid installed and working as a transparent server and I hacked at Apache for it to work with cgi's. I think maybe configuring the root Apache server and not the "~" Apache server is the issue. I am not really sure. If I could get a little help getting Squid's cachemgr.cgi to run in the "~" webserver I think that might take care of the issue? Also how would I get that to work without hacking around at it? Because I have no idea how to configure it.

cachemgr is trying to connect to Squid via localshot and you have the proxy listening on an specific interface. Remove the IP address in the http_port statement.
