I'll do one on Link Model B for now, and another for Link Model A later. Other than the eye colors, the current major problems are getting the undertunic to work properly (I passed that on to spinout... heh...) and his eye brow colors. I can't find the textures for his eyes and eyebrows anywhere in the data!
Model B of Link was only a texture change, actually. When Model B was designed, Nintendo knew they had the perfect model, so they just retextured it into what we see as Link today. So no modelling or remodelling was needed.
