After Updates 1/10, iBook crashing

Question

Hi, all
First Apple post
Bought my iBook G4 Jan 8 of last year. Now crashing
Installed updates, Jan 10 or 11, via CAT5 wire (AirPort disabled, running on battery for updates). Required reboot – booted okay. (Re-enabled AirPort right before shutting down.)
Next morning, wouldn’t turn on (no boot tone).
Reseated battery and it turned on but rectangular box I’ve never seen before declared I needed to reboot my computer (in about 5 different languages).
Rebooted and saw a tiny Finder folder in middle of screen that kept flashing from Finder folder to ?question mark? I didn’t know what this meant, but I just let it sit there, just in case it was running some sort of maintenance. After about 5 minutes, it rebooted all by itself and everything ran fine.
I immediately went into System Preferences, started Classic, and rebuilt the desktop.
Next morning, I started up okay and decided to go to discussion groups to post about my problems, but as I logged on with my Apple ID, the computer froze solid with the equivalent of a Windows Blue Screen Of Death (BSOD).
Apple BSOD screen data displayed:
System Failure: cpu=0; code=00000004 (No saveareas)

It mentions the CPU, the AirPort, and implies memory problems, but I can't tell if this means the updates (code) are mishandling memory, or the RAM is faulty, or the CPU is failing, or the AirPort is failing, or what.
Anyone have any ideas?
Or can anyone point me to any resources where I might delve deeper into this?
I'm a Windows/AMD/Intel technician who is trying to also learn Apple and various Linux distros. I understand hardware thoroughly, but new to Apple/OSX.
I love my iBook! Any help would be very much appreciated.

More info...
I tried to repair disk permissions in Disk Utility, but it fails after 1.3 of the way.
Can't repair disk.
Is there a bootable disk that will repair my hard drive?
Can I boot from my OSX CD and do a repair install?
I think the option to boot from CD instead of the hard drive is hold down the "C" key while booting. Is that right?
