Sigh, This may not be the first time I’ve asked a stupid question, what you say there are no stupid questions…well the reason I could not find where the textures are located in the Material, where they actually plug in is because in the Material Instance, I had the Parameter Groups Category found at the top of the MI closed, ie little arrow horizontal. Pop the down and there are all of the slots where the material are inserted. 
Oh well, I guess the second question could still be answered if anyone wants to.
