They drill for the neck and the bridge. The rest is up to you. It's pretty easy with a bit of patience.

They only finish in poly. I haven't used the in house finishing, but if it's like their old finisher, it doesn't get any thinner.

I defy anyone to prove that a contoured heel affects tone.

I have no experience with that Schaller but I personally would be inclined to go with a more standard offering.
