one more thing...
I had a similar experience - took 30 minutes with the Nook rep very slowly reading through a set of instructions, since the rep had never done it before. It's not a difficult process - they have a microSD card they insert, and then they reboot the unit.
There is no choice on the sizes of the two partitions - it's equally split - 8G for sideloads, 8G for B&N content.
