I say great find with the upgrades. Racks/panniers, barends and it's ready to go. Replace the fork when you get rountuit. Or not if you're into trail riding while on tour. GDT perfect, especially the tubeless tires.

Study up on pros/cons of tubeless before discarding. I'm thinking you could maximize the pressure in those and be just fine on pavement. Little slower, but touring is not a race, and as I understand them, tubeless are nearly flat proof with gook in them.
