for tanks go zerker/pally or sk if you are a boxer. as for the secondary a fury with mostly damage build or dirge/troub possibly even a ranger if you go paladin for maximum damage and aggro control but a fury gives aoe blocker which can give more zone clearing potential but be weary of a druid's issues of buff canceling and spells like sand whatever will cancel if you cast it twice too quickly so either have proper macros for them or triggers in act.
