Tuneup? (2006 Prius)

My roommate's care has a code for a misfire and looks like time for a tuneup.

Watched videos and does not look that hard. Involves taking apart the wiper assembly in a similar manner as when I replace the Inverter. I remember looking at the plugs when I did that job.

I do have a question however. Do I just need to likely replace the spark plugs or will I need to replace her coils at the same time?

When I have done tuneups on my Fords, I have replaced the wires but not the coil packs although I have replaced the coil packs on them when something seems strange with them. Ford coil packs are not for each plug but in blocks.
