If you're doing sneak, Ninja is worth it. Lone Wanderer's damage and defence boosts are also really good too. I wouldn't perk Awareness since it seems kind of a waste to me - why do you even need to know their resistances if your weapon only does physical damage anyway? Medic could be useful depending on how much you're in the open - if you're mainly relying on sneak, you're unlikely to need that health anyway, since you're not going to get caught.
