Osx 10.6.8 Slow After Power Outage

My 2007 intel imac lost power a while back and has been slow and somewhat erratic since that happened. My area suffered a power interuption that lasted a couple of minutes. When i turned the machine on the next day I used the disk utility to verify the disk and repaired permissions. the disk was fine but there were some permission errors which were repaired.After doing all that I found Finder could no longer search and find files, I could still access a file normaly but I could not search for a specific file or a group of files 9 .dmg for example)Firefox was very slow to fully load (30 seconds), one loaded the internet access was fine - 20 mbs or so. I downloaded the latest version of Firefox but it did no good.I had loaded Enequeue a week before the failure occured and that stopped woking. When i would click on a song in my library it would just hang.console error msg indicated the library had changed.A remote printer that had worked fine before the event was no longer reachable. I can see the printer but I can't print to it and if I try to modify the printer settings in CUPS I have to reload the printer driver on the remote machine (a 27" 2011 Imac) because that computer shows the printer as being paused.

All of this seems like it's either a permissions problem or a corrupt system file. I've done the following ton try and fix it Used Disk utility to verify the diskUse disk utility to repair disk permissionsDone a safe mode startReset all the plists.This older imac  is used mostly to access my music files on the new Imac, I then use the optical audio output to feed an outboard DAC attached to me stereo in the living room. The new imac is backed up daily but this one is not because it really doesn't have any data on it. It seems that i should be able to fix this without reinstalling everything. Both machines are running OSX 10.6.8.Is there anything else i can try or should i just reformat the disk and reinstall OSX?
