I bought the bulk pack which is 36 sq/ft which wasn't quite enough for what I wanted to do.  I had planned to do the entire floorboard from behind the second seat back and all four doors.  

There are a couple of different ways to do the doors.  The way I was told to do it is to put as much on the outside skin as possible, (which is hard because you have to cut it into strips and slip it through the holes) then about a foot square around the speaker.  I've also seen it where they do the entire inside of the door but I'm told that isn't necessary.

So I got the back done including as far up on the sides as I could get and 3 of the doors and ran out of stuff.  If I had not done the sides over the wheels in the back and only the floorboard I would have had enough but I figured that was a place where lots of road noise comes from so I went ahead and did them.

I bought mine from Ebay below cost.  I know what cost is because I sell the stuff.  It's crazy.  The guy I bought it from shipped it the same day and his price was very good.  I paid $130 including shipping for the kit which sells for $230 at Crutchfiled.  If you want the contact info for the place I bought mine I can send it to you.

There is also a similar product called Brown Bread http://www.b-quiet.com/brownbread.html that is less expensive and should work the same. I know the Dynamat stuff so I went with it.

If you want to go beyond the Dynamat (I used the Dynamat Extreme stuff BTW which is the best)look into Extreme liner also from Dynamat.  It is a lead based liner that goes over the Dynamat Extreme and blocks sound waves, where Dyanmat Extreme just dampens the vibration.  Together they make for a very quiet inside.

I hope that helps.
