If there was supposed to be a bonus reward for disarming/recovering all the sonic traps, there isn't. The end quest implies that either there are more traps left over, or we left some explode. Neither of those two situations happened.
I have no idea what you're talking about.
I think the bonus reward option is related to the first version of the quest. There were several incendiary devices set the explode that you had to disable. These were heavily bugged, and so were removed. AFAIK, the quest hasn't been updated.
She should be nicer and less crazy now.
