You /could/ do what I did, and force service checking on all your hosts by echoing a line for each host into nagios.cmd. See here: http://old.nagios.org/developerinfo/externalcommands/commandinfo.php?command_id=130
The other important thing to setup now, while you are thinking about it, is a sanity check for the Nagios service check frequency. This is much more important in distributed environments, but can be helpful at times like these.
We're pulling a little over 600 checks per minute total from two distributed nodes, and I have a simple (hackish) perl script that scans through the log file looking for 'EXTERNAL COMMAND' in the last 1, 5 and 15 minutes. It outputs perfdata, so pnp4nagios picks it up, and I have the warning and critical thresholds set ptetty low. That script is setup as a check command against the front end nodes. I even have pretty graphs now that tell me how many checks I'm doing on average, and how often someone bumps the queue repeatedly force- rechecking a host.
