One pound of rice makes ten 3/4 cup servings (1/4 cup dry, 3/4 cup cooked). So, for 400 people, you would need 40 pounds of rice for 400 people, if the serving size is the average 3/4 cup portion. If you want to allow 1 cup per serving, you would need to increase the amount of dry rice by 25%, which would be 50 pounds of rice.
6 ounces of white rice would be about 300-400 calories, on average.

This would depend on how you plan to serve the sandwiches. If you serve them on a plate with other foods, one plate per person, you would need 200 buns. It's always best to have extra, just in case you need them, so you would need about 10 extra. If you plan on having your guests prepare their own sandwiches in a buffet-style setting, you should have at least 300 buns to allow for 50% of your guests to come back for a second sandwich. If all your guests are adults and you really want to be on the safe side, have 400 buns to allow for seconds for everyone. You may end up with lots of extra buns, but you wouldn't have to worry about being embarrassed by running out of food and having unsatisfied guests.
