I'm missing something ? A spectator can only spectate and can't play. Sure that a bug may happen when you change it's team without killing him, when he can move on the map.

For func_door and func_door_rotating you should hook Ham_Use and not Ham_Touch.
For eliminating the "use" sound I think than you can filter it in PlayBackEvent, if you want that he can hear the sound and the others not.
