You know... I'd personally wait a week more. Really, as long as the airlock has settled, you don't have any obvious active fermentation, its a as much a matter of preference as anything else. Letting it set a week longer gives the yeast a chance to clean up a little more and may result in a cleaner flavor. Since it's your first, go with what you know. Next batch give it a week longer then have one side by side with your first batch to see which you like better. You'll be suprised the differences you can taste sometimes. Congrats on you first batch!
Will run for beer...
