Tip:
You should have some 3d making program at hand (like
gmax), load the model of the character that you want to change it\'s texture, and load the texture on it.
Now you can see how the texture goes on the character.
What I do from here, is paint parts in the texture in very contrasted colors (strong pink, blue, yellow, red, lime, black, white, etc). Then load them on the model.
Play with it a bit until every part of the body got a diffrent color. E.g. Left leg is yellow, right arm is blue, face are red, etc.
So now there\'s the skin base, and each part is seen very clearly even without loading the texture on the model in every small change. In Photoshop you can make the layers less opaque (only for convinient viewing), that way you can put one layer ontop the base layer, and edit the top layer (wich is half transparent) according to the color code.
It may seem like alot of work atfirst, but if you plan to make more than one skin, and to view the texture in an easy way, it really pays off.
Edit: Draklar beat me to it :O
