Welcome Stirling~
If both pots are full open and the neck is quieter, have you tried turning down the bridge pickup pot to balance them? As long as they're balanced, you should be able to adjust for less output with your amp/volume.
If the pickup is so quiet that you think there might be something wrong, you can easily disconnect the pickups and switch the connections. If the quietness moves to the bridge pickup when you swap the connections, you may well have something wrong with that one pickup.
Hope that makes sense... that's where I'd start, but there are some much more knowledgeable folk around here who will probably be responding shortly.
Lovely quilt on that maple- I'll leave the refinish questions to somebody who knows what they're talking about.
