Can't lay my hand on an old trip report I wrote, but you can reach Classe by city bus quite easily. You buy (or at least bought) tickets at a booth to the right of the train station as you exit. You then cross the street in front of the station, and, while facing the station, take the bus running to the right.

On the binoculars -- while we were there a group of Italian school children visited. One asked to try my binoculars, and they passed through the entire group before returning to me, along with many thanks.
