I have been reading, Aperture 1.5 - Professionally Manage Digital Photographs, so I can learn how to use this great application. I thought it might be hard going, but I have to say that this book is really easy to read and a lot of fun. I made a conscious effort to do every part from import to correction. I thought I knew about import, but even in that first chapter I learnt something. I would highly recommend this book if you want to learn Aperture.
