Edit: another question. When you import a new book into Calibre do you have to upload it yourself, or does Calibre automatically update for you?

Dropbox is sync software. If you have your Calibre library in your Dropbox it auto updates in real time. You will need to export it from your Dropbox to the Fire via the app.
