Wow. Thanks so much for your help. I ran DoubleDriver, but it hung up on a few entries, so I went back and deselected them and ran it again. I ran MozBackup for both Firefox and Thunderbird. One question regarding MozBackup: Do I just run the restore when I reinstall Firefox and Thunderbird to restore all settings? Does it restore all of my emails? I saved Belarc for reference later. I think I should clarify that I am reinstalling XP from scratch, so if there's anything that should do differently from what you've said, do let me know. Other than that, I've just downloaded every setup file for all of my apps, backed up app data such as my money manager, calendar files, fonts, etc. Is there anything else I'm missing?
Man, you guys rock! Normally I would be pulling my hair out at this point, but you all have made it SOOOO much more tolerable.
