Well, maybe he wants to do it simply for peace of mind. I did mine recently as I had no idea if they had been previously changed or not. Now I know.

I used a 6" chunk of rubber fuel line that just fit the top electrode on the plugs. Made it very easy to take the old ones out and to start the new plugs into the head. Very handy on the rear plugs.

To get at the rear plugs you need a good assortment of 3/8 drive adapters swivel ect. I did mine last week. Once you find a good combination for the back same setup work for all 4 plugs and its not that bad of a job. I'm sure there a best way to take the rear valve off too but you should be able to figure it out.
