Nice job, well narrated and illustrated. Did that myself twelve years ago, and the kitchen is still going strong. (Me, not quite so much.) My son owned a cabinet shop, so we did the cabinets, too.
A minor suggeston, which is a little late, but when you can, use ball valves for the water-supply stops. They mostly never wear out, which can't be said for the conventional angle valves.
Hope to see pix of the final product, and happy cooking!
