What's the Best Way to Get a Job I'm Interested In?

Dear Experts, I am currently a Senior in a college and am expecting to graduate in May 2009. I am also currently interning in a recruitment marketing department in a full-service advertising agency. I have a high interest in market research. Companies that I have a high interest in are Johnson & Johnson and P&G, as well as non profit "green collar" companies. With the current economy and job market (J&J recently went public about some layoffs), I would like to have some info regarding market research and pursuing that career.
