Nothing to worry about with the little holes WM, that is just a result of the air bubbles coming up to the surface after you were whacking the form. Next time, just keep going back and running the finish trowel over the surface HARD at an angle before the concrete sets up. That will get rid of the bubbles and provide a smooth surface. Your concrete will be plenty strong, have no fear. And your anchor bolts will be OK too. You're doing a heckuva good job there so far!
