For BCAA's, Arginine, and Glutamine to work for you, they usually are taken separately from protein sources.
I feel it's more effective that way, if thats true or not.
BCAAs are BCAAs. You are injesting them, or you're not. Taken separately, however, you have the ability to fine tune exactly what you injest and when.
If your protein source includes BCAAs and other amino acids in the amounts you'd be taking separately, then there is no need for additional supplementation. If you prefer taking them separately, shoot for a plain Jane protein and then add the select other nutrients and amounts of those nutrients that you choose. If your protein source does include all you would take as separate supplementation, you should really ensure the timing of your protein source is appropriate. The most obvious ispost-workout. Aside from that, there are varying philosophies as to when is appropriate for your other 1-2/day.
Unless you are really looking to fine tune your supplementation, taking a well-rounded, quality protein source is just fine. And for someone who is just starting to work out, fine tuning their supplementation isn't something they need to be concerned with just yet. Establishing proper form, eating well, and getting proper sleep are the most important habits to develop and stick to. Supplementation cycles constantly change and can change with your overall goals or current phase, etc. No reason to inundate anyone with that really.
From experience I've found it more important that you take the protein on a regular basis, rather than buying the most expensive type of protein. And to get me to take it on a regular basis it needs to taste good. Thus the Muscle milk. It's true its not the best, but it is good enough, doesn't break the bank, not loaded with sugar, and I don't have to hold my nose when I drink it.
Taking your protein source regularly is important. I think that's called sticking to the plan. If you deviate, don't be surprised when the results aren't optimal.
Muscle Milk has too many calories and too much fat for lean mass development in my opinion. I remember when my girlfriend was supplementing with it (because it tastes good) and not meeting her goals, her trainer finally asked what brand of protein she was taking. Then she told her to switch brands.

This is one serving of Muscle Milk in water. WATER.
High calories, high fat, low protein content.
By comparison, Optimum Nutrition's Pro Complex in water:

It's also an excellent source of all BCAAs and other aminos.
So that's a fantastic one.
Lean Mass Builder by ADS is amazing.
ADS is an amazing company. They are still newer but they know their stuff. No, they don't have 5 billion page ads in all the magazines like some companies (cough*Muscletech*cough), but they know what a quality product is.
Best cheap protein, in my opinion, or one of the best anyway, is EAS' plain Jane 100% whey.

It can be bought at most nutrition stores, various places online, or even Target for less than $20 for the 2 pounder. A five pound bag can be bought at Sam's Club for ~$27 and you can use that to refill the more convenient 2 pound container.
BSN's Syntha-6 is another one that isn't so great. It tastes good, but at the cost of your nutrition. And that shit's not even cheap. I wouldn't recommend it to anyone. And Muscle Milk is significantly worse than Syntha-6, so use that as reference.
The EAS, Pro Complex, and Lean Mass Builder all taste good. Not delicious good (like Muscle Milk or Syntha-6), but just good, and it won't gag you. That's just my opinion. I know a lot of people actually like the way Nitro-Tech tastes, but I have to disagree. Muscletech products are pretty decent, but I can't stand the way any of them taste, lol. And you are right, at least to the point that it has to taste good for you to take it. Most people will be the same, so by the lowest common denominator, for it to work, it has to taste good. I'll do something that's good for me that I don't necessarily enjoy, but most people won't. And why should anyone? There's a way to enjoy exercise, and there's a way to enjoy eating and supplementing.
