Hi John, I forgot number 5.... Once, you have a working rt-kernel, read up the linux schedulers (ie: CFS and CFQ). Then, tune those as well. As you would know working for redhat, these can be tuned after the kernel is compiled. There are methods to do this littered all over the internet. You can use all sorts of tools (cyclictest/signaltest/etc) to accurately see what effect your changes are making...then you test with your applications for "real-world" tests/performance. So, there is a learning curve. I would be lying, if i didn't acknowledge this, But once you have done it a few times, it is knowledge that you have, and won't have to re-learn. Then, it becomes very simple to do.
