Good news! I got it all figured out, thanks to a user's assistance on xda-developers.

First, enter the easter egg. On the welcome screen, repeatedly tap the top left then right.

Press "Android Development Settings" and then Enable "USB Debugging". Plug into your computer and run "adb devices" from the command prompt.
Your device should show, but say "unauthorized". Press "allow debugging" on the nook. run "adb devices" again and you should get a better result.
find a launcher such as RelauncherX and push it to the Nook using "adb install RelauncherX.apk".
Root the device with this package:

Disable the Boot animation because it's bugged and if you don't, you can't boot into anything. To do it, type these lines one at a time into the command prompt. When you type "su" you should get a prompt on the Nook to allow Superuser Access. Grant access permanently.
Code:
adb shell
su
mount -o remount, rw /system
mv /system/bin/bootanimation /system/bin/bootanimation.bak
reboot
after the reboot, verify you still have root by typing "adb shell" and "su" again. You shouldn't get a prompt on the Nook, and you shouldn't get an error in the command prompt.
To disable the welcome screen and initial setup, you have to enter a few more codes.
Code:
# pm disable com.nook.partner/.oobe.WelcomeScreenActivity
# pm disable com.nook.partner/.OobeLauncherActivity
Finally, when you Press Home, you will have a choice of Launchers. Nook or RelauncherX. Choose RelauncherX, then ALWAYS. That's it. You've bypassed registration completely. Unfortunately, the Nook Launcher is also the default E-reader. You need to use use "adb install" and install another ereader app to actually read books, because trying to launch the Nook app will put you back on the welcome screen. I recommend KoReader.
