What distro are you using? If you dont't mind installing another one for the proxy, you could just download specific proxy distros, such as Smoothwall or IPCop. They allow you to manage Squid through a friendly GUI. There is an add-on that is available for both, called "Advanced Proxy", that will surely fit your needs.
Have a look at these links:
