second question about clearing to lei shen and then joining the extended lockout: this should also be ok IF you don't do ANY of the early bosses on heroic. heroic lockouts are weird so if you do anything on heroic you won't be eligible for a different heroic lockout. as long as you stick to normal you should be fine.
