Do I have to have both gas bottles open?

When using the 250 MJ and 500 MJ manual dual stage regulator and the 160MJ dual-stage regulator kit, no, they can be either open or closed. As long as the cylinder in usage is open and both pigtails are connected. When the cylinder empties, the manual changeover valve is switched over and the corresponding gas cylinder should also be opened. 

If you are using the 400MJ auto dual stage regulator, to operate it the auto changeover, both are open.
