Hi Liz,
If it were me, (and a few years ago it would have been me, my twin boys could destroy anything as toddlers) I would go to my "Mail" app on my computer and on the left sidebar I would choose Reminders-->Notes, then I would copy all my notes and save them, maybe to an email to myself. Only then would I connect my iPod Touch to iTunes, let it backup and sync. Then, I would disconnect the iPod and copy/paste my notes from that email back into "Notes". At this point I could reconnect and backup and sync again.
There is a great little app called SimpleNote for $1.99 that has a web backup (for FREE) that is so simple. Google Simplenote and you'll find rave reviews. That way your notes are always saved.

I just noticed you are using Tiger. I hope this works for you. If you have been able to create and backup your notes to "Mail" previously, then it should work.
