If you use a T nut, and you use the boat in salt water, you might consider
using a stainless steel T nut. They have them at West Marine. Expensive, but
at least you won't get rust running down the padding.

Mine have bolts in the cushion board that
go into the boats fiberglass. Then inside the
fiberglass area there is a piece of wood for
a washer and nut holding it on.

Same here, more or less. Mine have a blind nut (like this:

side of the cushion's backing board with a machine screw going through it
from inside the padded side. The end of the screw serves as a stud to go
through the fiberglass. There's no backing board behind the fiberglass on
mine, just a fender washer and nut.
