Have autozone clear the codes and test drive. If the engine light comes back on have the codes read again and let us know.
If you haven't changed the spark plugs and plugs wires, do so. Assuming you can do this yourself, you don't want to pay the dealer to diagnose and replace these items $$$.
Replace plugs and wires with the same brand that came in the car (dealer parts, don't settle for OEM approved or lifetime warranty).
If the light went off the problem is no longer present. No need to worry, unless the light comes back on or you notice any problems with engine performance.
How many miles?

Not sure what you mean by this statement?
10k miles is very low. Once again don't be concerned about your car unless the engine light comes back on.
Do keep a record of the troublecodes (troublecode numbers and date) so if you have a problem down the road you can inform your mechanic.
If after a few days everything is okay, make sure you have a good battery for the winter ahead. If your car has the original battery now would be a good time for replacement. A cooling system flush and fill is nice also, not critical but good preventative maintenance.
I recommned against taking your car to the dealer for a problem you never noticed and your cars computer no longer detects.
I do recommend a tune-up if it's overdure. This is something that is needed periodically. The last thing you want is a couple hundred dollar troubleshooting bill, just to have the tech recommend a tune-up. The majority of the problem may have simply been caused by a little bad gas. Especially if you ran the car low on gas for the first time since it sat on the lot for 6 months.
