Pokémon Model Ripping Project

[trickyrick]

I'm currently testing out Blender Cycles render with ORAS models. Every single pokemon model package on Models Resource has the color texture, normals texture and a Body2 texture. How does one use this texture? Particularly in Blender node setup?
Also, any way to smooth up the shading on the model so it isn't blocky looking? Thanks.
