Welcome to Allpar. It should be pretty straight forward. If there is a plastic engine cover, it pulls up and off. Each coil unfastens with 2 screws and pulls up with the boot. Replace the plugs with what came out of it or what is recommended on the underhood sticker.
The plugs are platinum and should be good for 100K miles. If you will be doing your own work, you may want to get a service manual.

You shouldn't need more than just the spark plugs. Are you at 100,000 miles already?

The 300C Hemi should have 30K Champion coppers. The 3.5L has always had 100K platinums.
