That Mega Protein sounds pretty good, but a whey isolate will be far superior. Most stores like GNC, VitaminShoppe, Nutrition House have free samples of whey powders. See if you can score a few to try. I'm gonna guess you won't have a problem with whey. Try an unflavoured brand, I use Natural, with no artificial sweetners.
I will let you read about Glutamine here:

If you are training seriously hard, I recommend it. FYI: For supplements I recommend, a whey isolate protein powder, a multi-vitamin/mineral, extra chewable 500mg Vit. C, and Glutamine. That's about all you need. I take some extra minerals and digestive enzymes.
No blender, I just put the oatmeal and scoop of whey protein in a bowl, mix, add hot water, stir, add frozen blueberries, (or fresh cut kiwi, orange, banana, strawberries, etc.) some nat. yogurt, a tbsp of flax meal, some Udo's Oil and mix it up. Fast and super nutritious breakfast.
For protein shakes your buddy is right, don't pre-mix them. Put a scoop of whey in a shaker and add water when you want to drink it. Unless you are making a smoothie with fruit, etc. you don't need a blender. Just a shaker.
Same thing after training, have your whey and Glutamine already in shaker, add the Gatorade and shake.
