1) On Tuscan hills it's very hard to say which of the 3 has better coverage. Probably overall Wind has the best coverage, but it much depends on the zone you are going to. AndreA lives there so if you tell us exactly where you're going I'm sure he can help you more than me.

2) Wind has by far the best offers, but you probably won't have any 3G out of Florence and other bigger towns, maybe some EDGE.

3) This is always a problem with Italian cards. I live in Italy so I'm not much updated about it, some other non Italian guys here will help you more.

4) There are some plans with cheaper on net calls but usually they have very expensive off-net calls so they are not so good. There are options like the NoiWind one, with Wind, which offers a bundle of minutes to all other Wind numbers. All operators have similar offers, check on the pages here on PPGSM.
