As far as I can piece it out, com.apple.stadt.notify is a process which is meant to pass notification of a crash. It's crashing itself, and hence is being rebooted, and so on. There is a technical description of this here, though it's not really going to help you much (and it's over my head).
Frankly I think you are going to need to do a complete reinstall. You can probably get the install disks (which should have been included with the Mac) for a nominal fee by ringing the Apple Store at the number given at bottom left of this page and quoting the serial number of your Mac. Then do a complete reinstall of the system.

Thanks for the reply. I found that same info and feared a reinstall may be the conclusion. You wouldn't happen to know where the "status header file" that statd is looking for is located would you? I'd like to simply try to access it and see if it's a permission issue, corrupt file or a bad sector on the disk before going through the hassle of a reinstall.

I'd think, from the 'Input/output error', that the drive is giving trouble. After backing up, disk utility - verify disk - might show something, but you'd need to boot from another drive (perhaps a bootable clone, if the backup works properly) to try repair.
a 2008 air would have come with 10.5 at latest, so a retail 10.6 disk should be usable too, albeit there's no hardware test or ilife
