Where are the spark plugs located on a 2007 Toyota Camry LE V6 3.5 liter? How do i change them?

Please be specific, and not say, take out the old and put the new ones in. There are no Chilton books out on it yet. I'm going to order Denso Iridiums this thursday and need to know the process of replacing, because the dealer said, 150.00 just to replace the plugs, that's it, nothing else.

They are locate in holes in the center of each valve cover. You will need an extension on the plug socket to reach them as they are deep in the head. The back ones are tough to get to.
