1. Do you see any way to reward players for actions that are more difficult to measure (behaviour, leadership, social interaction etc.) and not necessarily related to combat or traditional level progression?

Reputation system and have your CSR's or whatever you wanna call em watch people and when they see something commendable they can submit it or reward it.

2. If a player (for any reason) was to be rewarded, in-game or out of game, what kind of reward(s) would you consider appropriate?

Seems Zin above me thought of everything I could think of, though cash seems weird to me. Maybe a free month or expansion for someone uber cool and helpful maybe.
