Henry...here is a video that covers some of the basics. I prefer to cover the whole floor with kraft paper or 15# felt and I use a pneumatic assisted stapler rather than a cleat nailer.
take your time when working the "rack" this is something I have seen many newbies screw up. "H" patterns and "stairs" from board ends that are not random can be very distracting.
Thanks for the help. I learned some stuff. Now to practice.
Also before you get into laying the floor spend some time securing the subfloor. Before I re-did my living room I added about 5 pounds of screws to the subfloor to fix some squeaks...its been about 8 years now...the squeaks have not returned.
