Are there any HOWTOS or recommendations anyone would suggestions that can help show me how to do a 2 load balancer set up (One Activate and one Fail Over) for three web server?
You mention CentOS, but is that the OS you're using? And while you COULD use pulse and piranha, you could also use the standard Apache mod_proxy_balancer module. The Apache documentation is a good place to start:
...since it has examples and explanations. There are also how-to guides for using it:
And personally, I'd configure heartbeat to do the failover of the load-balancer, but that's personal preference. These are all separate pieces, so there will not be a single 'complete' document showing you how to do exactly what you want. The number of servers is also irrelevant, since the load balancer can be handling loads for 20 servers, and heartbeat doesn't care what services it stops/starts to keep things working.
