No, you won't have ground loops... it's just a little um, pointless. :)
So by NEC you must run a dedicated ground from your panel all the way to the box where your outlets are, and ground the outlet AND The box there. This is to ensure if a short occurs inside the box it is grounded and trips the appropriate breaker.
You ran a separate ground wire to the receptacle... which is kind of pointless. :)
Your friend is right, they will be bonded at the box, but they would be anyway. The problem is you wanted a separate ground but you won't have it. Probalby the easiest solution at the beginning would have been to use plastic outlet boxes.
You only have to worry about ground loops when you have different potentials. Like if you hooked up some equipment to one outlet, and other equipment to a second outlet that had significant resistance between the two grounds.
Best,
Erik
