About the brushes. I have a set that I have come accustomed to that you can find my "tools" in my tutorial gallery. Tools allow you to tweak the brushes to suit your needs. So these brushes are mostly free around the internet. So a brush is really just a tool and like any tool, you have to learn how to use them. When you get a new set of brushes, play with them all. Find the ones you like and keep it. Throw the others away because they'll just clog up your workflow.
