Use BigSoccer! There are a whole lot of calcio fans on the boards here, many of whom live in Italy. You can talk to them to track Serie A this season.
One way I'm starting to familiarize myself with the Serie A is by participating in TreeItaliano's Serie A prediction league. It's free, and I think Tree might even have a prize for the prediction league winner at the of the season. http://www.goalleague.com/content.php?mode=home One source of basic info on the Serie A is ESPN's website. It's got standings and the occasional article on Serie A teams. http://soccernet.espn.go.com/section?id=europe&cc=5901
