We passed through Calabria on our way from Puglia to Sicily, and on our return from Sicily to Rome.
These were one night stops.
Westbound, we spent one night in Pizzo, a charming waterfront real working town with gorgeous views and a wonderful passagiata in the evening. Wished we could have given it more nights. We stayed at "Timpa B&B" which was not really a B&B, more like a hotel room with nearby cafe breakfast included. The views were outstanding, and the people watching from our balcony was great. I highly recommend spending a couple of nights in this town.
Northeast bound, we stayed one night in Maratea, at a hotel called Il Gabbiano. Spectacular setting right on the sea, with cliffs all around. We did not explore, because there was no real town without getting back into the car, but I understand there is a giant statue of Christ, and it's called the "town of 44 churches" (ha! did they ever visit Scicli in Sicily? they may have this record beat!). Anyway, cannot tell you much about Maratea except for the spectacular setting.
Have fun exploring!
P.S. There are a few trip reports over on Fodors forums that may help with your research.
