Well, that depends if you're a gunner or not.
The typical SDNer has been POTUS, has at least 3 noble prizes, a fields medal or two, been an astronaut cowboy (someone has to wrangle those loose asteroids since Bruce Willis died that Aerosmith movie). Don't mention your gold medals-they're a dime a dozen and just waste space on your application. Also, any research that doesn't result in curing a form or cancer or AIDS, isn't worth mentioning and will just make you look like you're reaching.
Also, make sure you've done something that shows a sense of civic duty/pride. Don't mention being a SEAL these days-everyone's done that. Delta is really what they want to see there. If you've ever saved the world, I'd mention that, but don't be flashy about it. I'd put it in your hobbies section.
Passable LORs would include the Secretary General of the UN, the Pope and Gandhi. Gandhi is preferred, obviously as he is dead and thus more difficult to obtain.
Good luck and let me know how your interview cycle goes!
