By not knowing anything about you I will say a few things.
Casein shake I would opt for whole food when you run out of casein. In fact at any point in time you can, I would opt for whole food. Your protein shake first thing in the morning would be better off adding in some food too. Same with preWO. The only time that I use a protein shake is postWO and that is Isotean. Otherwise only when I am in a pinch and cant get a whole food meal in I will go with Protean.
But like I said without knowing your stats I cant give much more info on F/C/P content.
