Also, a good series of educational videos is the 'Discmainia: Deep in the Game' on YouTube. It was a big help for me when I was trying to learn more.
Another great way to learn is by joining one of the weekly leagues. I like the friday traveling leagues, myself. Our community is great for teaching newer players. You can always post on here to see of there is anyone that would like to meet you for a round
