When you say, "Regular Oats", what kind of oats do you mean? I presume the 'quick' oats that you mix with water and stick in the microwave.
I'd change two things, otherwise. I'd ditch the Carafa - you've already got quite a lot of roasted grains in there, and it'll be quite black enough without the debittered black malt. I'd also save my EKG for aroma/dry-hopping purposes and sub another hops variety. You're using it for bittering, after all; why waste EKG, which has such a lovely flavor and aroma?
Flaked grains are difficult to include in an extract batch. There are no diastatic ingredients in the beer, which means that very little is actually extracted from the flaked grains. You'll get some of the oils and fatty acids from them, which will slightly enhance mouthfeel, but that's about it. I urge you to consider at least a partial mash whenever you use flaked grains; that way, you'll get all of the possible impact from the flaked grains.
