Not necessarily. Sorry for not expounding more on the rest of your questions.

It is slightly unlikely you will hit 2GB unless you are downloading a lot of pr0n. It is also highly unlikely you will hit 2GB just using Skype, browsing and playing Poker - unless you're doing it non-stop.

Plus, unless they have some kind of crazy proxy, they won't just shut you down if you exceed 2GB - they'll probably warn you first. Then you'll have an idea how much traffic you're generating doing what you are doing regularly. Most "kids" who go to college for the first time have no idea how much traffic they are generating - so I'm sure the abuse policy says you get warnings before they shut you down.
