Use it. squid is not that hard to setup if you do not have requirements like authentication or reverse-proxying. your case sounds quite simple; so what does not work? BTW: the linux high availability thing is a quite complex piece of software. If I were you, I would not experiment with squid AND HA at the same time.so not to add more to my email, I'm seeking advice about the proper way to learn about squid from A to Z if possible...
