One thing I've done in the past to help prevent 'configuration rot' of nagios configs is to hook it into the same files that drove our deployments - when the deployment changes, the nagios config changes with it. Nagios supports template-based configs so once the tests are developed it isn't too hard to write some automation that spits out a config file. This worked pretty well for a site with ~350 servers and devices (switches, APC rack PDU's) with ~3000 tests.
