p90x Nutrition plan - how do I calculate it?

Hi, Im starting the p90x plan on Sunday and Im so confused about the nutritional plan. It says I need a protein bar, ((the site says Clif Builder's 20g Protein Bar can replace the one they want me to buy from them)) but, does that count as one my proteins I need ((Im a phase 3, I need 9 in a day)) And my recovery drink, how do I add that in there, I was told chocolate milk can be used as that.. Do I could that as one dairy too?

Any and all advice would be helpful. Thanks
