Help with Material Creation

Hello Unity users

I've installed Unity and decided to import my mesh into the engine. I have diffuse, specular, normal and displacement maps. I created a material but I cannot find a shader for combining all of them. All I could make is only diffuse and normals....

 

I think this requires you to paste code to make the shader (something I am unfamiliar with) but perhaps it could help. No displacement still, but do people usually combine displacement maps with normal maps? I've never worked with displacement before.
