Time Machine single handedly destroys all of my files. HELP!

Question

After transferring my entire 60GB hard drive to my new Lacie 500GB external drive, and performing a clean reinstallment of osx (since nobody answered my last question) on my p.o.s. emac, I went to work on setting up Time Machine (before transferring files, I partitioned 160 GBs of the hard drive for it, while using the a second partition to house all of my files).
With a clean computer, and all of my stuff sealed safely away on the hard drive, I attempted to get time machine to do it's innitial back up (back up of very little, since I had just wiped my main drive) and it would fail at about 60% (two hours later) because of an unspecified error. I trashed the partial files on the partition, and tried several times, with similar results. Finally I decided to "erase" the Time Machine partition, and it litereally erased it (it dissapeared, no longer mounted). So I ejected my other partition that housed ALL OF MY FILES, and tried to remount them.
They wouldn't mount, but showed up in disk utility, and after some persuasion I was able to mount both the time machine partition and the external hard drive partition, and decided that things had become a bit too unstable to be comfortable, so I decided to start transferring my files off of the external hard drive and back on to my main one. Beginning with my pictures folder (a 3 hour transfer), I returned home to find my computer crashed. That's right, old fashioned FROZEN MOUSE, MESSAGE UP TELLING ME TO REBOOT os9 system error 11 style, while the file transfer had 4 minutes remaining. So I rebooted, unable to eject the hard drive propperly, and when the computer came back up I found most of the transferred files to be corrupted, and no sign of the Lacie hard drive.
In disk utility, I found that the names of my two partitions had both changed to something generic like disk010, and wouldn't mount. Upon trying to verify or repair, I recieve the following:
Invalid B-tree node size
Volume check failed.
Error: The underlying task reported failure on exit
1 HFS volume checked
1 volume could not be repaired because of an error
So I try DiskWarrior and get the following:
"The drive is too severely damaged to rebuild."
Is Data Rescue II my last bastian of hope in this matter? What in God's name went wrong?

Hello anti:
This is not an answer since I had problems following what you did. For starters, you should update your profile since I assume you are running OS X 10.5. I have no clue what a p.o.s eMac is - could you be more specific?
The multiple steps you seem to have taken have apparently clobbered the directories. If DiskWarrior cannot fix the issues, then I know of no other software that would address the corruption.
