One major piece of advice would be not to start this unless you're serious about putting the time in, because it is a long learning curve.
If you do decide to go ahead with this, I'm glad we caught you early - here's a warning:
Don't become a spammer
Put good content on your site
Listen to the more respected members of this forum
Don't listen to the people who have a post count of 2 and they both say "get more backlinks"
You'll do just fine
