In the mean time you can buy some great videos from audioschoolonline.com
they have some of the best videos I have come across. Also some great books to pick up, "The Art of Mixing" by David Gibson and "The Mixing Engineers Handbook" by Bobby Owsinski are some of the best books I've ever read about mixing.
These are mainly about mixing techniques and not about Reason. You can apply any of these mixing techniques within any DAW. It's all about the mixing techniques if you want that "pro" sound.
