To fix the shadow on this one I used the magic wand tool in PSE9 to get the shadow areas selecting areas going down the photo and in the space by his arm a bit at a time. I used 3 px feather with this. As it will pick little bits and pieces of the hair you need to be careful in those areas not to remove what you don't want to remove. I just used the selection tool to give me a pretty good outline and make my next step easier. I then cloned out each area being careful to clone from areas nearby where I was working so the colors would match better. After cloning you may find a little shadow left. Carefully clone those out with a small brush. If you need to get color to match better in some places either use cloning or the healing brush.
