I have no experience with Photoshop. I do have a similar program, Corel Draw that does about the same thing. It will do amazing things BUT it is not easy to use. I'm self taught and it shows. It can do far more than I know how to make it do. I've noticed that there seem to be various versions of PS based on pricing. Likely the cheaper versions do less of the awesome stuff. The version of PS that does the really neat stuff is quite expensive. If you're going to make that investment you should look for someone in your area that can give you lessons.
Photoshop is a high end/professional program designed for graphic artists, professional photographers, etc. The current version is in the Adobe Creative Suite . There's a link on that page next to the Photoshop box to try it for free. You could give it a whirl and see if it's something you could work with.
