Here are my thoughts...
You are better off getting a solid photography book, such as the unofficial POTN Bible, Understanding Exposure by Bryan Peterson. As you read a book like that which is fundamentally about photography and is camera agnostic, you will see how the settings relate to each other and the effect of the changes you make. By following along with your camera and trying out some of the things that are discussed in the book, you can see how your equipment reacts and start to get a feel for how best to use it for you and your photography.
If you understand Shutter, Aperture, and ISO, and how to use them to get the shot you want, the camera's manual itself should be enough to fill in the blanks about the specific functions of your camera.
I have found generically that a lot of those "helper" books are riddled with inaccuracies as they just copy/paste old books and don't really do a great job updating them.
