1) Which end of the shield should be grounded? I know this is a generic question but I'm struggling with it. I know I should only ground one end of the shield to avoid ground loops, but which end? Lets say I'm running a shielded wire from my preamp board to a volume pot. Should the shield be grounded at the pot or at the board?

2) How many leads for a mono 1/4" audio jack? Since the barrel of the 1/4" plug is ground, can I just connect the shield and use a single conductor inside for the signal (tip)? Or, would it be better to run two-conductor shielded wire from the jack to the preamp board with the ground and signal on shielded conductors with yet another connection to ground for the shield itself?
Just connect the screen to the barrel and the core to the tip. That'll work just fine. Try to ensure that the jack is isolated from the chassis to avoid ground looks though. The plastic sockets are best for this.
