Just as an update for everyone. I successfully installed Nagios and the NRPE plug-in to monitor my LMCE installation. Nagios has all of the features I want, and it has a nice easy to read web interface for the 'non-technical' folks in my family as well. It allows me to monitor the health of all of my systems, as well as Internet status. Now, when the wife is having problems on the Internet, she can pull this up in her browser and see if the problem is in-house or somewhere else. I can also see how the LMCE environment is performing (processes, load, disk utilization, etc). One thing to note during the installation. NRPE wants to install xinetd. Don't do this, or it will break LMCE. You'll need to install NRPE w/o xinetd and run it as a daemon on the core and media directors. Other than that, everything works great.
