Welcome samatizer!
Great advice from FrankenWashie too.
The only thing I'll add re: the pickup wire hole is that it shouldn't require drilling all the way through to the control cavity.
Just drill as near to the bottom of the pickup route as you can get, and just far enough that the bit it intersects the existing hole.
Depending on your level of experience, trying to drill a fresh hole all the way through can end in tears if you miss the cavity!![]()
