I hate to tell you to RTFM, but the QGIS team has put a lot of effort into the User Guide and very practical Training Manual.

If you're already familiar with typical GIS workflows, you'll breeze through them, and they'll help you wrap your head around the QGIS way of doing things.

And if you're into books, Locate Press is run by some of the original QGIS authors, and many of their books are very QGIS centric.
