I woke up last night, concerned that the programming pads were incorrectly oriented on the board, but my concerns were invalid. A check this morning confirmed that all was well.

I did notice that the current configuration is for a Slave/Source. Slave units are better suited to be the battery operated end, so it looks like I will be creating the wireless guitar pack first instead of the headphones. Not a huge issue, but not what I had intended on creating first. I should have created a Master/Source unit, or a Slave/Sink unit. Next will be the Master/Sink unit, to complete what is now the guitar pack.
