In order to teach English in Italy, you'll need to obtain TEFL certification. After getting it you will be illegible to teach English in classrooms. TEFL certification is easy to get, and is often offered as a post-graduate class at college for those planning on teaching abroad. Those who ignore getting certified will have to look for a good position for quite a long period of time.
One thing that sets Italy apart from other foreign countries is the fact that in order to get a teaching job, a personal interview is a must. You will have to talk to your future employer in personal, and only after that he will or will not hire you. This means you should plan your time- and your budget- around making a trip to Italy for interview purposes.
If you seek for adventures, you may come to the country even before you actually start looking for a job. But if you have any doubts about getting hired, or if you want to make sure everything is lined up before you actually move abroad, you should plan on a few trips back and forth.
You'll also need to obtain an Italian work visa. Like in the other EU countries it may be time consuming and difficult procedure. Be prepared to provide any and all documentation of things like marriage, citizenship, and graduation from school. You should better start the process as soon as possible, to have plenty of time for traveling and getting accustomed with local life.
