You don't have to get protein powder, but I recommend it. Considering how much protein we have to consume in a day, its kind of rough getting it all from food. You really have to pack away the food to get the amount of protein you need.
When I make scrambled eggs, I usually just beat up 5-6 full eggs. Put them in a skillet and cook them. I am sure if you really wanted to be a stickler, you could try and seperate the yolk from the whites, but thats beyond the level of precision I go.
A good rule of thumb for how much protein you should have early on is basically 1 gram per pound of your bodyweight. Which is actually pretty accurate. I am on Level 3, so it suggests that I consume 9 servings of protein.
1 scoop protein powder = 24g of protein. 9x24 = 216. I started at 209lbs. So its pretty close.
So if you don't want to get protein powder, you can just try to find a way to consume Xg of protein where X is your bodyweight. Whether that is in eggs, turkey, or whatever else you wish to substitute in there. I just remember when I ran out of powder, I felt like I was eating for like 4 people to hit my protein marks.
As for the serving sizes and which counts for what...
You have to play that one by ear, so to speak. Generally, if you had 1 serving of something...it would be 1 serving. It would not be 2 servings (1 snack, 1 dairy). So you could place it wherever was most convienent to you. Like if its easier for you to eat carrots as a snack, so you can have cottage cheese with your dinner, that is an option as well. The main purpose is trying to limit how much IN GENERAL that you are consuming in a specific group.
If you are taking supplements, its almost more important to watch the calories instead of the exact ratio of fruit/vege/dairy. The ratios that they give via the amount of servings is trying to make sure you get your proper vitamins to support a rigorous workout. If you are already getting some using a multivitamin, they have a secondary function of fatless calories for your body to burn.
Yeah, I type lengthy posts....
