Hi Troy,
The main thing is not to overdo it. Adding too much of any of these specialty grains can easily ruin a beer.
Start with, say, 250g of roasted barley. You might also want to think about doing a combination of chocolate malt, black malt and roasted barley.
If you do a search you'll find a few threads with others' experiences. Even the all-grain recipes you'll find will give you an idea about quantities.
I assume you were thinking about starting with a stout kit? The other option is to use a Coopers Lager kit or other lightly hopped kit as the base then add some grain and hops to achieve a stout.
Cheers,
Oliver
