Dead Drive, Kernel Panic, PLEASE HELP!

I have a Power Mac G5 with a150GB disk and a 250 GB disk. Both came orinigally with the Power Mac. The startup disk, the 150GB, was running slowly. (I am running OSX 10.4x.) I used Tech Tools 4.0 to try and optimize the disk, but the program said that the 150gb startup disk was unsupported hardware, and could not optimize or maintain a stratup disk anyway.

The tech tools program suggested I make an "e-drive" and boot from that, which I did. I was still unable to optimize as tech tools said ithe 150gb drive was "unsupported hardware", but it did let me run the "maintenance" feature. I did that and it suggested some node changes which I allowed hoping that was the cause of the slow performance.

After that I was unable to startup the computer. I got the kernel panic gray screen "you need to restart the computer, or hold the power button for ten seconds".

I did that numerous times, shut the computer down, unplugged the peripherals....,nothing worked.

I then installed OSX on the other drive (booting up from the cd) and made it the startup. I tried to use disk utility to repair the 150gb disk and got the following message:

"invalid b-tree node size
volume check failed
error-The underlying task reported failure on exit "

The biggest problem is that I had very important photographs on my 150gb that I had not backed up. (I would also like all my Itunes.) If I cannot fix the disk, I don't mind replacing it as long as I can get access to my files, especially the photgraphs.

At least I can use the computer with the 250gb as the main drive.

I am lost as to what to do next to retrieve the files or fix the drive. I would appreciate any help. Thanks in advance to anyone who can save me!

I tried disk warrior. It said the drive directory was too damaged to rebuild.
it looks like I used anolder version of tech tools and that changed extensions, or something like that.
i found a warning on the apple site about not using older versions of tech tools or of norton on tiger 10.4x

How do i get to single user mode on the damaged disk, now that i have changed the startup disk to the 250 gb disk.
i had tried single user before but i did not see a command prompt. the message was that it was "hanging"
it was the first time had tried single user. Is the command prompt the same as in DOS?
Thanks.
