Karen, Welcome! I also came from a film background, starting out with a Canon FTB (which I still own) and then a Nikon FE. After that first Nikon I got bit by NAS and have not looked back since. I agree, there are many articles and books to mention. I like Scott Kelby's Photoshop CS6 for Photographer's Book. I would take advantage of the free 30 day trials of Capture NX2, Adobe Photoshop, & Adobe Lightroom. You may also want to check out NAPP (National Association of Photoshop Professionals). It costs $99 to be a member. Not sure if they offer a free trial membership. Best of luck.
