Changing spark plugs on a 07 ss 5.3l

Hi I was looking at my engine bay today and wondering how the back spark plugs are accessed to change them. They look completely hidden. Also is there a problem with the steel threads on the spark plug "freezing" in the aluminum spark plug hole. If this is true then maybe it would be wise to change the plugs at the 50,000 mile point. What are your thoughts?
