I'll save Mr. Sloper some problems, and tell you the first thing you need to do is hit the back button and read the Stickies - particularly the FAQ and Breaking in parts.
There are some excellent written guides that will answer where (or if) you should go to college, what to study, what to do if you live in an area with 0% industry, whether math is important, and so much more.
Second, naming a studio is not a job idea. Do your research: Go to the websites of these studios, find their career page, look at the titles and requirements and figure out what you enjoy doing.
Practically speaking, chances are you won't be working for the huge studios right out of college, but the skills you learn trying will help you land the first job.
