Back to Italy? Last year I spent two weeks in Tuscany, south of Florence. I went through the Chianti region, Siena, and south to Pitigliano, then into Umbria (Spoleto, Assisi, and the Monte Sibilini area). Very pretty country, lots of history for me to soak up, and a great place to tour. Northern Tuscany (Lucca and points north) is supposed to be very scenic, and not as touristy as central/southern Tuscany.
I'm planning a longer tour next spring to include Sicily, Sardinia and Corsica, I'm really looking forward to it.
