For Tuscany in general, visit www.turismo.intoscana.it; for Umbria visit www.umbria-turismo.it.
For major events where tickets should be procured well before arriving on the spot, check out Box Office at tel. 055-210-804 or www.boxol.it. They will only deliver tickets to an Italian address, but you can buy ahead of time and pick them up at the booth when you arrive.
Dealing with Strikes
It's always a good idea in Italy to double-check the official hours that museums and sites are open, and to confirm airline, train, and bus reservations the day before traveling. What's open or running today may be closed tomorrow, as strikes can close attractions and shut down public transportation without much warning. For information on pending strikes, visit www.slowtrav.com/blog/italy_transport_strikes.
