Lots of good stuff in your post, but the particular bit above is wrong. It's 8.5' from the top of our baseboard to the ceiling. (the baseboards are boards that is directly applied to the shiplap (roughly 9" x .8").) The drywall currently sits on top of the baseboard which sits almost 1/2" proud of the drywall face.
