There's a lot of magazines. Check out 'Digital Pro PHOTO', Picture and American Photo if you want to follow where the line was drawn a month ago.
For books, I recommend Scott Kelby's Photoshop for Digital Photographers, Ron Reznick's Digital Photography (an e-book) and Bruce Fraser's Camera RAW. If you are an absolute beginner, I'd suggest also a book that describes the basic functions of a camera. Although it is film based, Adam's Camera and Lens is possibly the best for that, but there are many choices.
And don't forget the forums! In addition to this one, there is an obscure forum focusing on Digital Photography Reviews run by some British guy that often has news and opinions about various equipment.
