Very good summary.
One issue/solution you might consider adding:
You will lose the cover image when side-loading ebooks onto the SD card. To keep your cover image, simply use calibre and convert epub to epub. Then transfer the file over to your nook.
Every ebook I acquire goes through that process before I put it onto my nook.
