Too many questions, that have related/unrelated answers.
If you will have a 12v electrical system, you will most likely need the side terminal on the foot-starter switch. That lead goes directly to the coil, giving 12v going to the points while you are cranking/starting. You then have a ballast resistor between your ignition switch and the coil, so when you are driving there is around 8-9v going to points (otherwise, 12v will burn the points).
"Also I've never seen a knob adjustment on a distributor like this. Which made me question 6v/12v."
That is the vacuum advance control for the distributor - needed 6v/12v.
"I'm planning on a 12v coil, my condenser and points shouldn't care witch, correct?"
- points do not care, as long as you have a ballast resistor
- condenser might be different 12v/6v - wait to hear from others (or, just buy a 56-63 235/261 condenser).
Go ahead and spin that 6v generator with no wires attached.
How will you run current to the 12v battery (to keep it charged).
Check the Tech Tip (top menu, above) on 6v to 12v conversion.
