DO not add bakers chocolate, it will leave a nice gross fatty film on the top... you dont want that. Id increase the oatmeal to .75-1lb, and remove the hop additions at 30 min and 10 min. If you want a stout, you dont want to overpower tha flavor and aroma with hops, you want the malt to come through. Bitter it at 60 minutes sufficiently, and forget the other 2 hop additions. I have never seen wheat in a stout, but you can also use some 6 row pale or maris otter.... Wheat will help with the head though. Do what you like, it is your beer, just suggestions!
