The presets are usually hidden inside the pot shafts and can be adjusted by pulling the user knob and sticking a long skinny flathead screwdriver down the hollow shaft.

You want to adjust the RG static magnets so the colors overlap at the center like you say. Normally you do RG then converge B over them. I've heard of people moving the blue away but in practice there's often enough interaction that RG needs touched up if you do. What I do is have blue close unplug the cathode wire to kill blue (turning down G2, or using a 100K resistor to mute a gun are also options) convergence RF then turn blue back on and converge it with RG.

Not the chromatic button the set, the chroma button on the pattern generator. Pressing is supposed to remove any color signal from the generator, so the set receives a pure B&W signal.
