Those arent Crazy prices lol, for a shop to do it, 100 is a little steep for that, try bringing it to a different shop, it will cost your around 1.75 cents if you can figure out how to do it your self. there are threads on here for you to look at on how to change out spark plugs
and yes he is talking about a coilpack im assuming, the price he gave you is legit it seems like, i dont know the exact price for one off hand, but that sounds reasonable

Different things besides the ignition can cause a cylinder misfire. How many miles are on the car now? The V6's don't require a plug change until 100K miles. You can start with doing some diagnostics to eliminate things without spending any money. First, clear the code from the PCM. Swap the plug from cyl 1 to another cyl and see if the misfire code moves to the other cyl. If not, swap the cyl 1 coil to another cyl and see what happens. If the code stays with cyl 1, something else is creating the misfire. If the code moves with the swapped component, that is the problem part.
Heavy carbon buildup on the piston, a clogged injector, a marginally working O2 sensor, a vacuum leak - any of these can cause a misfire.

So we're talking about a v-6 Charger here and what year? The check engine light coming on coincided with your oil change? If so, check your plug wires that none are obviously loose, could have been bumped by the tech, also check if any oil is puddled up on the coil or wire & boot, the tech could have spilled oil.....
