Hi Paul. I live nearby and have ridden all those roads, most of them many times. New England cycling is quite different from the wide-open spaces of the west and mid-west; it is no accident that organized U.S. bike touring began in Vermont.
The towns are close together, rarely more than 30 minutes ride between. You do not have to carry food and water for the whole day. The roads form a dense network, so we can almost always choose a route that avoids heavy traffic.
Camping, both public and private, is plentiful. The popular campgrounds fill early in peak seasons, so plan to call ahead. Food can be any style you want, from a sub at the convenience store to gourmet dining.
Sights to see? It depends on what you like to look at. Foliage, waterfalls, museums, college campuses, and recreational shopping are all thick upon the ground. Adventure Cycling missed a great opportunity to mark on their maps the garage where Ben & Jerry's began, just three blocks off the route in Burlington .
