Flop c/r is a good idea since MP is going to autobet this flop like 98% of the time. I dont know about the c/3bet though, after SB calls 2 anyway. You might be ahead but your equity is slim- a safe turn might be better- I'm not sure about that. I think you have to bet the river, however with the large pot I think I pay off a raise- I think it's a missed straight or flush draw (or weaker ten) often enough getting 17:1.
