Question [Q] Nook HD+ Rooting and Romming Help

Ok I'm not entirely sure where to start with rooting and flashing a new rom onto one of these fancy tablets and i'm used to dealing with phones where there are a bunch of sticky posts leading to wikis and such not of how to do this yet i see no such sticky posts so i was curious if someone could point me in the proper direction of where to get started with rooting one of these and then flashing cyanogenmod onto it.

Also a side question from the owner/user of this tablet, is there a way to install the stock rom onto a bootable microSD card to be able to keep the stock apps and stuff or should i just be able to make backups of the stock apps, namely officesuite, with titanium backup once the device is rooted?

Thanks in advance for any and all help.
