Go <a href="http://www.bjcp.org/styles04/Category13.html">here</a> for the style guidelines, which tell you what a 'stout' is, according to the BJCP. Basically you need some roastiness, which you should be able to achieve with your oven and some trial and error grain burning. (obviously don't burn them, but you might plan ahead for that sort of possibility) My earlier post about my ideas on roasting should work (I think). I've never done it myself, but it is based on some methods I've seen floating about the web. Basically you want to carmelize the grain.
I would try to dry your grains with the help of a fan. You don't want them to go moldy.
You shouldn't have a problem using all oats, but I would malt at least 85-90% of them. Even the best malts with high enzymatic power can only handle converting an additional 20-30% unmalted grains.
Take a look at some stout recipes (beertools.com has a ton) to see what percentage of roast grains you'll want to use. 10lbs total seems about right. I might short the roast grains the first time in case your kilning method imparts more bitterness than the professionals might.
Good luck dude!
