carpet install...any tips?

No glue for me. I insulate the floor pan, as Abodyjoe says, because the stuff it comes with is never enough. Instead of a screwdriver from the bottom, though, I heat a large nail or bolt red hot and poke it through and wiggle it to enlarge the hole enough. It leaves a clean hole and absolutely no fraying. any spots not accessible from the bottom, I find the hole with a pin, then push the heated nail through from the top. Works very well.
