Ok so this is my first ever sprinkler installation design. I have made a map of my backyard and I think that I have everything ready.
I am just going to hook a hose up to my faucet (with a vacuum breaker) and have it lead to a pvc pipe which will go underground into a zone box. I tested the faucet and the psi is at 50 and the GPM is 6.8

Now I have a couple of questions for the community. I am thinking of installing these sprinklers throughout my entire lawn. ( http://www.sprinklerwarehouse.com/Hunter-Sprinkler-Spray-Body-p/pros-06-prs30.htm )
I will be using two nozzles, one for a 10' radius and another for a 15' radius.

Here are my questions...
Will the setup that I have so far work? (See picture below)
How should I split up my zones?
Should I have my zone box close to the backyard where all my sprinklers are or closer to my faucet which is by my house?
How many sprinklers should I have per zone?

Here is my floor plan so far. Red circles indicate possible sprinklers and blue circles indicate the sprinkler radius.
