Software :: My Safari Update Crashed Nothing Works

I've got iMac PowerPC G5, running OS X 10.4.11.

I ran an update two days ago (Nov 30, 2009) for iTunes and Safari. The iTunes update installed, but the Safari update failed. Now none of the main Mac software will run, including Update, Mail, Safari, or iTunes. The icons just bounce once and do not proceed with the application. Thank goodness for Firefox.

What should I do? I've downloaded the MaxOSXUpdCombo10.4.11PPC.dmg today, but can't run it. I've already tried to run the auto update through Utility Terminal, and while it said it was updating I'm still not getting anything to open. I tried deleted the Safari phist and and History files from Library Preferences, but that didn't help.

I ran Disk Utility to Verify Disk Permissions and Repair, and everything ran without any error messages. Interestingly, when I click on either of the two disk icons (149.1 GB ST3160023As) and (Macintosh HD), neither will allow the Repair Disk icon on Disk Utility to work, it stays shaded.

I again ran Disk Utility and this time clicked on the top Disk Drive and then clicked "Verify Disk". A window popped up saying "First Aid Failed - Disk Utility stopped verifying Macintosh HD because the following error was encountered: The underlying task reported failure to exit"

Below this, here's what Disk Utility Reported:

Please help. Honestly, all I did was run auto update. I have the original system disks, and can run them if someone shows me how to fix this, as long as I'm not risking all my photos and files, etc. Yes, I should buy an external drive, will do.
