To amplify on what iGary said: not an Archive and Install, not an Update, but an Erase and Install, (Erase=Initialize) which will flatten your machine back to the stock configuration (All data will be lost).
In fact: I woul boot from the OS DVD, and after the first response choosing Language, do not proceed with the install, but go to the Installer menu at the top, choose Disk Utility, choose the hard drive icon, go to Partition and delete all partitions, creat a single new Partition, then go to Erase and re-format the volume as a Macintosh Extended (HFS+) volume. Then go ahead with an install of the OS.
The un-repairable errors you have reported indicate that the logical structure of the hard drive volume is b0rked. IMPORTANT: No amount of reinstalling will solve this, short of erasing the disk completely and starting over. This is why you were spinning your wheels reinstalling earlier.
If the problem persists after a reformatting of the hard drive, then it indicates a probable hardware failure in the hard drive, cable, ATA controller or RAM.
