Find and download a copy of Fabral's installation manual, follow it's recommandation's.
Predrilling the fastening pattern saves time, it is counter intuitive. But it does.

Screws are a definite, I had not thought about the pre-drilling that is a good idea!

Pre drilling is a very good plan. You need to add extra screws around the perimeter but that is easy to do.
You end up with a roof with a very symmetrical screw pattern that is easy to inspect to find missed screws.
Pre drilling takes time but that is recovered when installing the tin. There should be fewer wandering screw starts to damage the surface and allow rust to begin.

Stack all relevent sheets in a pile with the bottom edge aligned lay out the screw pattern on the top sheet Then drill all sheets together with a 1/8 inch bit.
Get lots of bits because they get dull fairly fast.

Another minor time saver is to drill one top corner with a 3/16" or 1/4" bit, big enough you can slide a hook into when you pull the sheets up off the ground.
