Yes, the first layer is deadener. I covered around 70 percent of the entire floor using strips and strategically placed squares and patches. Some folks go with less, some folks cover everything.
The next layer for me was closed cell foam.
After that, I put jute pad and carpet which has an option called "mass backed" which means the underside of it is really heavy on the plastic material that binds the fibers. They say that helps to further deaden sound. Edit: and open holes in the firewall transmit a huge amound of noise.
I made sure to fix evey one of those too.
