Create your _D and _D2 texture for the character.
From those your can generate yout normal map _n and your specular maps _s, in GIMP or some other graphic program.
Place them in the folder with the character and set up the FPE file for it. ( Use a stock character one for a templete).
Apply a character based shader (this is important or it might not work) and then tweak the shader.
The FPSC community guide has a section by Lee on how to change the shaders for characters.
Bond1 has great tutorials on texture creations. You could also search for character in the forum and a bunch of stuff will come up to aid you.
Hope this helps.
