Basically, I would suggest a Squid reverse proxy as a front-end to your system. Have it use a redirector like SquidGuard to distribute requests across multiple backend web servers, and if you need to distribute your database load as well, set up a single master mysql server which replicates to read-only servers on each of the load balanced Apache servers. And if you are getting really crazy traffic, you could round robin across multiple frontend squid servers. But I would be very surprised if you are doing anything that is getting that much traffic.
