Default [Q] Upgrade Rooted Tablet

I have a rooted Nook 16GB tablet and I'd like to do a full flash and not even have the Barnes And Noble on there. Awhile ago I used this thread to do everything and I've been using it since then.

I'd like to install cm10 or a higher stable version but not sure which guide I need to follow to do so. Any help would be great! Thanks!
