That's wonderful... I have an uncle who lives in Australia.
If you're worried about the various commutes, one thing you might actually find interesting is the CalTrans website. It's the website the California Department of Transportation has and it covers California as a whole. One of the tabs off the main page is titled "Travel." From there, they actually have quite a few live traffic web cams. If you choose a "point A" and a "Point B," just set your clocks to Pacific time and tune in. It might give you a realistic idea of how long it's going to take to travel from an area near the beach to Riverside.
A word of caution, if you really have your heart set on living near the beach, be forewarned... the toll of commuting daily for your husband will begin to show very quickly. An 8-hour work day compounded by commuting 2 hours each way will not leave much time for the family.
Good luck to you and your family... what a wonderful adventure you're in for!
