I need to do an oil change

Spark plugs should only need changing at around 100,000 miles, but check your service schedule in the owners manual as some will last 150,000 miles. Oil change should also be listed in the owners manual. Normally engine oil, and oil filter should be changed together at 3000 miles with conventional oil, while Full synthetic oil will last to 5000 miles. Always replace the filter when you change the oil. Oil change is not really a tune up item. A tune up is usually for the spark/ignition system components.

Spark plugs are recommended to be replaced every 90,000 miles. You do not have to replace the oil filter when changing the oil. That's up to you. In 99% of oil changes the filter is replaced.
