I'd carb just as you would normally; I'm a huge fan of nitro stouts, but I'm not going to invest in getting all the equipment together until I've proven to myself that I can consistently produce beers that I feel would be enhanced by the entire setup. Stouts with CO2 can be wonderful as well, so unless you have the facilities already, I'd just go with that. I'll actually be bottle-conditioning (due in part to the sheer amount of beer I ended up with) and figure that, given enough time, they'll be terrific in their own right.
2.4 vols should be fine for a stout, so I wouldn't tweak anything, especially if you have something else on tap at the same time. I'll probably undercarb slightly on mine just because the extended time in the bottle can lead to increased risk of long-term bombs, which would be doubly unpleasant with a beer this dark.
