Soma New Express or C Line tires in 38mm (actually 36-37, depending on rim) will give a great ride and fit under the fenders. New Express are a bit lighter than C Lines, but a bit more expensive. The stainless front rack that Soma sells will fit your mid-fork braze ons (so will the Nitto front racks). The one that Velo Orange sells won't fit, although their Constructeur front rack will work (mounts to the dropout eyelets). The Constructeur rear rack matches and also will stiffen your rear fenders, for no rattles over the worst roads.
