That web site has pretty good instructions. The nails for the floor
nailer will be 2" - 3" long, but they go in at a 45° angle, more or
less, so the vertical penetration is about half the nail length.
Depending on your subfloor, you will probably never touch the joists. On
the other hand, having the nails over the joists might make the floor
squeak less.
Read the instructions that come with your flooring. They will tell you
what type of nails to use and how to space them. You need to do it as
instructed to protect your warranty.
