As a matter of fact there is no need whatever to get italian (or any other EU country) citizenship, if you are a citizen of any country in the EU you only need to register to the local authority as resident (after 3 months of staying).
If you really want the italian citizenship, you can ask for it after 4 years of (registered) residency in Italy.
