We've discovered(from a bloke's barbie cookbook) that you can cook pizza in the barbie, so I'm guessing the same would apply to naan! We use baking paper & before adding toppings, cook one side very briefly then turn pizza over, add toppings & cook for 5-8 mintutes with the lid down (of course). Works a treat. For the naan though I think probably cook on one side only. Will post if I get round to cooking naan.
