Though I haven't learned Italian, I can say that, complementing my Spanish classes, I learned from watching common movies (usually Disney, since I knew a lot of them anyways) with Spanish subtitles, and it does take some getting used to, especially the speed and pronunciation (and that whole vosotros thing, but we don't like to talk about that). So imo, a great way to learn Italian, especially if you are using something to help you learn it, is to watch, like Tom said, a movie in your native language, then Italian with Italian subtitles, or even just a movie that you own if you're able to change the language. Not quite sure how you would practice your speaking, but I think in the beginning it's more important to learn the basic vocabulary, sentence structures, and conjugations before trying to speak proficiently.
I know my thoughts kind of run on, but it's finals week, so I've slept little and studied much, so give me a break D:
