QoS is a way to throttle some network services from eating a disproportionate amount of bandwidth, especially if VOIP or videochat services are being used.
If someone is stealing your bandwidth then whose the meathead? WPA and mac addy filtering is the best thing to do for a router if it has a wireless AP.
But the problem is not that a person can steal the router is that the person owning the router gets owned because they have no clue of what is happening.
So instead of setting up QoS setup your router properly.
