Well, if you bought CS4, then you might as well learn how to use it. It looks daunting at first, and it is. I started with Photoshop 10 years ago and it sat on my computer for two years before I bought a book and ground my way through some of the basics. You can't learn it all, or even very fast, it's just too huge and powerfull for one person to learn it all. But buy the CS4 Bible as a reference, and when you want to do something, look up how to do it. Another great way is to Google what you want to do. There are a million free tutorials out there for every concievable task you will ever want to do in CS4. Just Google sharpening in cs4 and noise reduction in cs4.
