... Norton Utilities is the only application (that I know of) that runs in OS 9 but is actually certified to work with OS X partitions. I don't know if DiskWarrior is certified to work with OS X partitions. And you CAN preview fixes in Norton Utilites before it fixes them -- you just need to enable that feature in the preferences.
I think Norton Utilities will probably be decent, but remember, as sithious said, you DO NOT want to rename files that start with a period. UNIX uses the period at the beginning of a sentence to signify that it is invisible. So make sure you turn on the preview of fixes before you fix your OS X partition.
A better bet, though, would probably be Drive 10. Although it did not get spectacular reviews, it is built specifically for OS X and ignore problems like the . at the beginning of file names that UNIX uses. Drive 10 is basically a precursor to an OS X compatible TechTool Pro. It's the only drive utility built for OS X right now, though. So I would suggest that.
