You're welcome...
As for PhotoShop being enough, it depends upon what you want to do, really. For painting things in the digital medium, there has to be something better. PhotoShop is mainly for editing photos and existing images instead of painting objects from the ground up. A lot of furs use PhotoShop for their artwork and seem to do alright with it, but they'd probably have an easier time of using programs that are specialised for painting instead of editing.
PhotoShop is great for web design, at least. I usually use it for layout, presentation, and graphic design purposes, rather than bothering to finish artwork in it.
