George, I'm sure you already know what I best recall from EE school and years of experience, but hey its been years NO WARRANTY:
The coil ONLY ramps up to a high enough voltage such that current arc jumps the plug gap and the energy (Volts x Amps x Time) is dissipated .
The voltage necessary for current to arc jump the plug gap is a function of A) The Plug gap B) The medium (fuel compression etc) in which the arc occurs
The wider the plug gap the higher the coil voltage, so to reduce that LOWER THE PLUG GAP
Your questions:
So my question is what brand and what plug type(plug number) can I buy to reduce coil voltage on my 4.3L GMC ?
I don't see the brand as a major factor in reducing coil voltage..but Im no plug expert nor do I have any specs
And what type of plug wires will reduce the coil voltage?
I don't envision types of plug wires reducing coil voltage significantly HOWEVER types such as pure copper or carbon core or resistive or other suppressor wires can absorb some of the spark energy in the form of heat losses (I Squared R) versus more of it across the plug gap when it fires.
Would reducing the plug gap reduce the coil voltage??
YES
There ya go George this is ONLY my best recollection it may be right it may be wrong, hope it helps

Today's Featured Article - More Memories of a Field Service Engineer - by Brian Dye. Introduction: The author worked for one of the largest Ford tractor dealerships in England as a trouble-shooter on tractor engines, hydraulics and combine harvesters from 1963 to 1972. In 1972 he became a dealer manager and finally left the dealer net in 1975 to run his own electronic design and manufacturing company. [Editor] We live right in the middle of Norfolk.
