I'm another one that relies on Calibre. Whenever I get a new book, I add it to Calibre to remove the DRM and convert to epub if it came from Amazon (I've been buying quite a bit from Amazon lately). My Calibre library is backed up nightly (with other important files, photos, etc.) onto another drive, and periodically backed up to 2 other drives. Some of the books are in Dropbox in case I have to reset my reader while away from home (never happened yet, probably because I'm prepared for it).

I used to go back and edit each book with corrections after reading them, but it was getting too time-consuming, time I decided at my age that I'd rather spend reading a new book. I will still do it for some of my favorite books though.

As for my favorite authors and being aware of their new books, most all of them have a website you can sign up at to get notified of new releases, that works out very well for me. A lot I find just browsing books, but the email notices mean I don't miss anything I've been waiting for without spending time searching.

Edit: One other big thing I do is to add an extra column in Calibre for the date I finished a book. Just clicking in the box enters the day's date. That lets me keep track of which books I've read, and if I sort the books by that column, it's easy enough to see how many books I've read in any given year.
