Tires don't need to be rotated yet, leave that to be done at six or seven thousand miles. Just check your air pressure, and give everything else a visual inspection.
Anyone can change the oil, so long as he is competent and uses the correct oil and filter (changing the crush washer is advisable too).
Make sure you get a service order, receipt, or other document clearly stating that service was done in case you are given problems (likely will be) by the dealer if and when you take your car in for warranty service.
Oh, and tell him to fill the new filter with oil before screwing it back on.
