I don't have a suggestion for your booting problem other than trying
to boot from a CD or netbooting and seeing if you can mount the root
file system to get a better idea of what is wrong with it. You may
just need to fsck the root partition or it could be something more
egregious like a missing/corrupted boot block or similar.

I'd suggest that you try putting the disk which is acting squirrelly
onto a separate scsi chain (so it does not have other drives to
interfere with) if possible; that will give you a better idea of
whether you can get it mounted and get the data off of it.
Good luck with your further trouble-shooting.
