(Note: When I mentioned borrowing a boot DVD earlier, I meant TechTool Pro, not OS X, in case that wasn't clear.)
For the invalid node structure errors, Diskwarrior will usually do the trick (but that doesn't come cheap either). You can also try just cloning your drive to another using Carbon Copy Cloner, Super Duper, etc, reformatting the original, and cloning back. Assuming the file system damage isn't too severe, that should work. As for the 6 GB that doesn't show up at all, you didn't answer my earlier questions, but if you're reaching PSU limits I'm not sure you'd want to waste power on a 6 GB drive anyway.
Also, this should be a good lesson to do regular backups. If you do have complete backups, you can always just reformat the drive(s) and restore.
