Hey Justin,
Congrats on getting your degree! Iano's generic advise is very good, although you shouldn't count too much on accomplishing much through headhunting outfits. A recruiter I used to use told me once that most recruiting firms, especially those on-line versions, receive up to 25-35,000 resumes per job posting. Unless there is something truly outstanding in your cv, the odds are long that you will get lost in the sauce. Telephone follow-ups are good, if you can get a real phone number... Once you get experience, of course, generally the recruiters will come to you if they have specific needs.
Starting out, my first suggestion would be to check your uni's career center (most schools have one). At the same time, start slogging through the internet for companies that work in whichever field you want to specialize in. Don't forget local and federal government agencies - these often have entry-level positions, and can be a good way to get some experience under your belt. You should also consider whether you want to stay in the US, or are willing to go overseas - there are a lot of good entry-level positions available if you can somehow translate your academic experience into something the donor organizations want. Especially if you speak a language besides English.
For a science career, think very seriously about an advanced degree. Most of the best bio jobs are going to require MSc or even PhD and post-doc. Just the way the market is.
Anyway, if you have more specific questions, feel free to ask. The first step is going to be to decide exactly what you want to do, then look for places that are hiring for those jobs. Don't get frustrated, it can be a very lengthy process - especially given the state of the US economy today.
