Right...or wrong? I read somewhere I need "Fill" and "Dump" valves..but don't quite understand that...

You need TWO valves per bag for individual fill/dump control on each bag. One to fill and one to dump.
You asked about closing the valve to fill the bag ... how would you make this work? If you planned on a direct line from the tank into the bag, with no valve, then the bag is gonna "equalize" at whatever pressure your tank is holding. And you will have no control over the rate of fill ... in other words, no TWEAKING of the pressure or ride height.
Think of it this way ... one valve is like a faucet ... you open it and air flows into the bag. You can control the rate or flow by "bumping" the switch ... thus controlling the pressure, which in turn controls the ride height. The second valve is like a drain. You can open it wide open, and dump ALL the air ... or you can "bump" it and gradually let out the air ... same as the fill valve, adjusting the pressure.
You CAN use two valves, setting up your system to control either FRONT for one pair of valves and REAR for the other set. Or , I suppose, you could set your system up so each pair of valves control one SIDE or the other. (right / left) I dunno why one would want to set their system up with a side to side control only though. Setting your system up this way is the same as described above, but now, each PAIR of valves control a PAIR of bags as opposed to an individual bag. You would hit the FILL valve and the front would rise ... hit the DUMP valve and the front would fall.
