I visited this WHS in August 2013. Following Els' review, I did my research to have at least the name of the streets closest to the two sites near Spoleto. Still it was not easy to find them! Tempietto del Clitunno is just beside the motorway in Campello sul Clitunno, around 12km from Spoleto. The rear side of the temple is visible from the motorway. It is only open in the afternoon on certain weekdays and costs 2 euros to visit. It is kept in very good condition and I was happy to pay the entrance fee knowing that I was directly funding it (since it is managed locally and not by the region). Then I visited the Basilica of San Salvatore just outside Spoleto near a new cemetery. Just park near the cemetery and walk 200 metres to the Basilica, otherwise it will take ages to get there by car since almost all roads are one way! The entrance to this desacrated church is free and both the exterior and interior are austere. You can see the different styles and columns coming from previous buildings on the same site. The several leaflets and information I was given from Spoleto's tourist information centre helped a great deal appreciate the details of this WHS and hopefully I'll be able to visit more sites in the near future.
