Adobe Photoshop Elements is a great tool for photo enthusiasts getting into more serious editing. The latest version -- 7.0, for PCs only ($100, street, full version; $80, upgrade) -- makes organizing easier. Editing starts at a simple level and builds to greater complexity, so you can do more as you learn more. If you want to try shooting RAW images, Elements' take on Photoshop's Camera RAW converter is a great way to get your feet wet. But the biggest improvement is in compositing, which had been quite limited in other versions.
