Backing up notes/homepage icons for a restore?

[Delia]

I've had my iPod Touch since Feb, and it's been fine-- no big issues, since this past week where I noticed the Calendar completely spazzed out and duplicated a day's worth of reminders-- alerts and all, for every day left in the year.

I want to run a restore on the Touch, but I was wondering if there's a way to back up/save/preserve the Notes, hand-entered contacts, and possibly home buttons when I go to restore.

I've restored my iPod video plenty of times, but I'm new to troubleshooting the Touch and wanted to find out if these items can be backed up.

Thanks!
