I've been told that B&N's DRM is compatible with ADE, so you shouldn't have any trouble transferring even DRM-encumbered files, whether by entering an ADE account on your Kobo, or otherwise dealing with DRM.
Once you're using the Kobo with Calibre, you'll find it has a lot more flexibility than B&N devices. The ability to map tags or other metadata to shelves makes finding books much easier. You will also be able to view and manipulate series information easily. You can also update Calibre from the device for things like reading progress.
