Thanks again for all the help. Any suggestions on my follow up
question:
"Secondly,
when hanging the sheets do I have to install all the screws in each
sheet before moving to the next or can I put a few in to hold the
sheet in place then move to the next until its all up?. I plan on
driving a screw every 12 inches. "

As rico says, doesn't really matter so suit yourself.

The one thing avoid is getting a hump in it so start at one edge
(preferably the one next to the previous sheet) and work across and down...
