Default plug change

after you change the plugs,

should I put dielectric grease on the wire fittings?

Should I put it on the threads as well?

Applying dielectric grease on the spark plug terminal is good idea.
For the spark plug threads, first see how well the plugs screw into the hole before putting anything on the threads. Sometime the plugs fit very tight. I've had to put lightweight oil on plug threads to get them to turn smoothly.

Tech62571,
I just put new spark plugs in my 2700 w/ a 454. I used one of those little grease packets NAPA sells at the counter for spark plug caps and boots. She fired right up after winter storage. I would highly recommend using in any marine environment.

I agree with the others on using the dielectric grease on the terminal to wire jacket. I don't use anything on the plugs threads.

It wouldn't hurt to put a tiny bit of grease on the threads to prevent seizing and ease the change the next time around. Unluck auto mechanics, any machine screw (aka bolt) in a marine environment (particularly saltwater) really needs to tiny dab of grease on the threads before assembly. It eases removal in the future and prevents shearing bolts.

PS-lock washers should also be used when using grease on the threads.

You right to use something in all the threads.
