Bought a Kobo Aura, now what (re: Calibre)?

I recently bought a Kobo Aura and am a long time Calibre user (on my Samsung tablet). Is there a 'now that you have a Kobo Aura, here's what you do to make Calibre play nicely with it' guide for newbies?

I added the Kobo utility plugin to Calibre, but don't want to start futzing with it until I have at least a bit of a clue as to the potential outcome.

Thanks.
