I disagree. Unless you know that the new plugs have an antiseize coating, a thin coating of antiseize should go on the threads. Steel threads in any aluminum hole should get this treatment. There are too many documented cases of stuck plugs in aluminum heads to push this step aside.

Otherwise, yes to the dielectric grease and hand-starting the threads.

Removal may be tricky. Twist the boot to break the bond to the ceramic before pulling. When pulling you have to grab the boot at the right spot so the wire doesn't come off the terminal. Consider investing in a special wrench for this. Use two hands to unscrew the spark plug, as you don't want to bend the spark plug and break it.

Torque is tricky. Because of the antiseize I torque to feel. Snug may be the word to describe it.
