Hi Dan,
You adjust the voltage across the CCS using the cathode resistor of the 7788 (set at 125 ohm in your schematic). There are three factors at work here: the current through the triode, which is fixed by the CCS; the cathode bias; and the plate-cathode voltage. By altering the bias, you also alter the plate-cathode voltage.
Regarding stoppers, the way you have connected the g2 stopper to the plate stopper is right, i.e. each stopper should be independent. Do the same thing with the suppressor, maybe using 1.5k as a stopper.
