A note on using anti-seize on the spark plugs, most modern plugs already have a coating on the threads that works as an anti-seize. Anti-seize will also cause incorrect torque down of the spark plugs. I do not use anti-seize on spark plugs.
If you feel like replacing the coil packs at the same time, you can get a pair of the for around $35 (May 2016) on Amazon: http://amzn.to/22Bd3qy If I had the time, I would have probably replaced these at the same time, this car has 150,000 miles on it and it couldn’t hurt.
