I agree with Michelle 100%. The only time that I EVER go out of LAX is when I fly to Orlando non -stop, as the fares are often much cheaper than the non stops out of SNA.
This is just to let you know, that there is one other option other than SNA. Especially if you will be getting a rental car. That is Burbank (Airport Code: BUR). It is one of the older airports in the area (I always loved it as a kid, as it was often featured on I LOVE LUCY!) hehe.
BUR is just up the 5 freeway on Hollywood Blvd, in Burbank. From Burbank to Anaheim, it typically takes about 40 minutes, although I do find that baggage seems to come out quicker there, than at SNA. It is also less crowded.
Some of the best fares that I've seen are as follows.
PHX to SNA -Aloha Airlines - $66.50 including all taxes, except for September 11 fee of $2.50 per segment. Must purchase both directions by August 31. You can also travel until December with a fare of $83.50 and more flight options. (Travelocity.com)
PHX to SNA - Aloha Airlines - Fare of $82 on Aloha Airlines, almost all the time (

PHX to BUR -America West - $78 until November, but has some restrictive date availability.(
