You can start your dog on raw at any age. Some breeders ween their pups onto raw.

RMB (not RBM) - Raw Meaty Bone
MM - Muscle Meat (Meat, no bone)
OM - Organ Meat (liver, kidney)

As for rotation, I think it is balance over time. Each meat has different nutrients, so you want to give a good variety of food to your pup so that you make sure he is getting the nutrition that he needs. Personally, I feed my dogs several different meat sources each week (and each day for that matter). They sometimes get different meats in the same meal. But, everyone has their own way of feeding, so not everyone will do it that way, I'm sure. It is what works best for you and your dog.

ETA: I definitely agree that when starting out you should start out with one protein source and add new ones one at a time.

You can start out with any meat...we did chicken which is cheap and easy. You will have to do both RMB and MM to begin with - depending on what type of RMB (chicken quarter, wing, neck) you choose you will need to add a certain amout of MM (chicken breast, thigh meat, gizzards, hearts). The reason being, those RMB's have different amounts of bone to them - chicken quarters have a pretty good ratio of RMB:MM, where necks are very boney. Too much bone will lead to constipation; Too much meat = runny poop. So, you will need to add a bit of MM if you were going to feed chicken necks. Each week or two you can add a new protein source (assuming your dog has had no problems with the previous meat added) until you get a good variety (then you can feed them all together or in any order). The only reason I say to wait on the OM, is that it is very rich and can also cause runny poop if you give too much. You only give a small amount at a time. We waited a couple of weeks into the diet to add that in.
