California has earthquake requirements not found elsewhere. Hold-downs need to be placed during the pour. And, yes, a footing makes sense, particularly if you ever intend to add a 2nd story.

Is the electrical underground or overhead? If under, you will have to bring the lines into the house, through the foundation too. A basic primer: http://en.wikipedia.org/wiki/Shallow_foundation

Do you anticipate a gas line for a BBQ? Better get that in the plans for the plumbers so they can stub it out for adding the final connections later.

Do you anticipate water issues (yes, there is a drought but ...)? If so, now is the time to anticipate French drain systems, which can impact your excavation and backfill.

Here is a good drawing for a slab on grade with footer (12"deep).

Up here we call Villa's photo is a pan slab and our slab on grade is more like this with a footing down to frost level.
We use the pan slab for real poor soil conditions
