cambridgeincolour.com/tutorialsI personally am a huge fan of the book "Understanding Exposure" by Bryan Peterson
Aside from those, shoot, experiment with settings to see what they do (I'm a proponent of starting in priority modes to get a solid understanding of what aperture does, then shutter, and then play with manual if you want to, but if you're in manual and just lining up the arrow with the center, you're learning nothing).
Youtube's a great resource. If you have an adobe subscription, their videos are awesome. Basically, just dive in, start searching shit out, learning about it and practicing it.
Don't expect awesomeness at first, it takes time, but with time and effort you'll get it.
Also, there are three photo 101 assignments posted on /p/ now that you can try out.
