rested bonus is not used while getting RAF bonus. I also do not think there is any range denominator on the triple xp, you either get xp for the kill or you do not get xp, range is not a factor as far as I am aware. From reading here, a lot of people that do not loot, just park their toons at the entrance and clear the instance. Personally I normally keep my toons at the start of each section in SM and only move once that section is cleared.
