I have a D5200, and was in the same boat as you a while back. Outside of just reading a ton of stuff online (all free), and taking a beginners DSLR photography course, I actually thought the D5200 Field Guide that I bought in Amazon was worth it. The guy who wrote mine doesn't have one for your model, but there are a few others that are under $15 and have great reviews. Once you understand aperture, depth of field, and ISO, things get easier. I still think that composition is the hardest part about photography.
Joey, what's your opinion of Ken Rockwell? To me, he comes off a bit pompous in a lot of his writing, which put me off. I know others feel the same way, based on what I was reading about him on other forums. I disagree with some of the items he mentions on his D3200 page, personally.
