I don't mean to steal your thunder but I'm going to post the link you provided to check your own credit score for free.

You get to check it one time for free every 12 months.
I haven't gotten my SSN in the mail yet, so I can't check. But I think I will wait a few months, then I will check it. I aim for high credit.
