Very nice. Give the hubs some oil; that will help the shifting. Also check Sheldon Brown's English 3 speed page.

The stem on your Sports looks dangerously over extended, though. I'd push it in some more.

For tires and tubes, there are many options for the Sports; it takes 650A or 590 or 26" x 1-3/8 tires and tubes. They are available. The Tourist takes a 28" tire; that may take some doing to find tires and tubes locally.
