There aren't a lot of bus companies in the US anymore. Greyhound and Trailways are the only two that come to mind. You'll have to see if they have web sites and which one serves the areas you want to see. Our train system is not much better but can get you from coast to coast. If you are from Italy, driving here is not a big problem since we drive on the right side, too. Find out what insurance and license requirements are first. Lots of car rental companies but they will want a credit card for your deposit and you'll most likely have to be 25. Have a good trip; this is a big country with lots to see.
Greyhound is the only one that serves the entire U.S. Depending on where you are there are several bus companies that can get you from place to place. There is Megabus on the east coast and midwest, Jefferson Lines in the midwest, Peter Pan on the east coast, several Trailways outfits.
