You may need to shrink the size of the mustache itself because on a preset, the images really get maxed out and fill up a large amount of the body.
For the eyebrows, you will need to move them down a little bit as well, and for the rim around his ear, you will need to use the section of the UV map in the upper right hand corner, as that is the back of the head. You can easily shrink the nose as well, but I'm not really sure about what you mean about the "lack of lining."
