//- are pins 6 and 7 on the opamps really supposed to be jumped with no resistor?

yes,short jump,no resistor.

//- grounding of the input and output plugs. Does the ground plug go to the vgnd rail or to the ground on the breadboard?
- could the channel crosstalk be happening through the vGnd rail?

yes,vGnd rail is the amp board ground.
