ron,
I once considered moving to Italy, but after reading This Website, I came to the conclusion that it probably wouldn't be as much fun as I first imagined (although it would probably be a very interesting "life experience"). I can't remember the details of your initial posts - which city are you living in?
Aside from the Permesso di Soggiorno and other "residency" details, one of the parts that seemed most intimidating for me was exactly what you mentioned - the "everyday normal stuff" like electricity or internet service, as well as finding Doctors or Dentists. According to the website, Dentists are especially in short supply and many do not speak English. While it sounded like a good idea at first, I came to conclusion that it would be better to just continue visiting Italy. However, I am still considering a stay of perhaps one or two months to study Italian (perhaps next year?).
You're fortunate that you have support from your company, and probably others that have gone through the same experience. At least in your situation you know that your stay there is finite, and therefore you'll be back home at some point in the future.
As a previous reply mentioned, you'll probably get over being homesick after a while, perhaps after you get into somewhat of a "daily routine" with social contacts in the place you're living.
Good luck!
