Hi Calvin!
I would suggest you to start with Google Adwords first. It's easier and faster to get your ads approved and in most cases it is cheaper. You can have your Ad running with Google Adwords in minutes, as on the otherside it could take up to 5 business days to get approved at Overture. You can start your bid as low as $0.05 at Google, as on the otherside your minimum bid on Overture is $0.10. So there are a lot more facts to start with Google and as you learn how to play the PPC game, you can ad Overture in addition. Keep in mind you have to track and follow your ads very carefully to find where your winners and loosers. It first starts with your Keywords. I use
Adwords Analyzer to find the best keywords for my niche. You also have to learn some rules before you start, because you could also loose money faster than you can look. I highly recommend the
Google Cash ebook as start. As a bonus now they have included an interview with Jonathan Mizel and Adwords "Guru" Perry Marshall, where Perry reveals some of his hottest tricks how to survive in the Adwords Game.
Please feel free to ask, if you still have more questions.
All the best
