I'm looking forward to seeing your layout. I like the mat you've chosen for under the tank. That looks nice. As another owner of a bookshelf tank that actually sits on a bookshelf, you're likely to get a little water on and around the bookshelf, so if you have expensive or rare books below the tank, you might want to cover them or move them while doing water changes, trimmings after it has been flooded, etc.
Good luck with your project. I'm subscribed.
