I'm not convinced by the above, as it starts with reading the manual for the camera. They're generally not well written, not very interesting, and if you know nothing about photography then a lot of it will just be confusing.
You need to learn about photography, not your camera. i.e. you need to understand concepts like sensitivity, aperture, focal length and shutter speed.
Then you can have a lot if fun with your DSLR, and you'll understand how it does the things it does. It'll be much more rewarding.
Hope that helps.
