Texturing a dragon

Hey everyone,
I got in some problems while texturing the my dragon using UV mapping. The textures does some how apply to every face PLUS the UV-mapping.
The intention was to apply 3 different UV-layers:
color= feet, body
normal=body
alpha = tail

Does anyone know what trouble I’ve gotten myself into?

See the .blend file and you will understand.
