Jones bars are a little bit redneck for what you are after. City bar, maybe Moustache bar, is the style I think you are going for. I would take advantage of the fact that you will be using flat bar brake levers to 'upgrade' the calipers to V-Brakes. Those are old style cantilevers on there now. An acquired taste. 650B isn't so much a size of tire as it's a size of wheel diameter. You won't be able to change from 650B tires as long as you keep those wheels (which I recommend you do). I'm eyeballing those tires at 35mm to 40mm wide (and tall), and it looks like wider tires were on there before. There is no good reason to run the fenders so far from the tire. You've got room under there to go to 50mm possibly. The bike shop could tell you for certain.
