Wipe and re-install Android 2.2 on Droid2?
I ended up figuring it out, but it took a lot of research and time. Here's what I did, probably not exactly like this since it took me a few tries to get right:

Root your phone.

Download the Koush Bootstrapper/loader and install it onto your phone, via their site or the Android Market.

Go to Team DeFuse's website to download the Fission 2.2 ZIP file. Put this on your SD card somewhere.

Boot into Koush, apply the bootloader patch, and then reboot into the bootloader.

Clear cache/data, mount /data and /system, clear cache/data again, install update, select ZIP file on SD card, once that's done, clear cache/data again, and then reboot.

You should then boot into a fresh install of "vanilla" Froyo Android. No apps. No settings. And best of all, no Motoblur!

... I think I got all that right. If I missed something, let me know.
