I can try and put something together. Hopefully it will help. I honestly kept this as basic as possible. Also, here are tutorials I used to help me out:

There was a video I used that I found on Youtube, and for the life of me I can’t anymore. There were two things though that I took away from it that helped me a ton. One, was before I added any maps to the maya fast sss shader, I made sure a light map was created. For some reason Maya won’t include a light map with the shader. Well, happens sometimes for me anyways. And secondly, again before adding maps, I mess with the Algorithm controls in the shader’s Attribute editor. It helps mostly with how the light is affected.
Ah, found it:
