Welcome to Apple Support Communities
Insert your Install DVD and go to: Apple > System Preferences > Startup Disk > select the Mac OS X Install DVD and click Restart.
Be patient... If you think your iMac is running slow wait until you see how long it takes to boot and how slow things run from the DVD.
Once booted from the DVD, skip the Installer and open Disk Utility from the menu bar. Then in Disk Utility, select your Macintosh HD, select the First Aid tab and click the Repair Disk button.
It should only take a minute or so at most to boot from the DVD.
If your sure you have the correct Install Disk for that iMac, I'd start over. Then if it still doesn't work then perhaps a trip to your Local Apple Service Provider with the Disk or Disk and iMac is in order.
Alternately using the correct Disk as per the following article, see if you can run the Apple Hardware Test? > http://support.apple.com/kb/HT1509

This was the problem. I have the discs separated but somehow mixed them up. Once I installed the correct one, it worked fine. I had seen this solution earlier but was mistakenly certain that I had the correct disc.
All is back to normal now, including the peppiness.
