I use Quick Oats for my recipes that require oats. They are are broken into smaller pieces and are more readily dissolved in water. No cooking is required for quick oats, just toss them in the mash...

Absolutely right.  Fact is, you can even use instant oats to brew with. 
Old fashioned rolled oats and especially pinhead (aka steelcut) oats need to be well cooked first.

And I'm sure it's great for my health, a bowl of oatmeal in every glass.

Throw some molasses in the boil and you've got Breakfast Stout!

I don't think they need to be.  Only if you want to get the fermentables out of them, which isn't really my concern.  They'll still impart their flavor/mouthfeel to the beer without cooking them first.
