CA Alimony and child support? And who is the custodial parent?

You need a lawyer. While child support is going to be a given, I'm not sure she'll get alimony since she has a job and an independent income. Be a good father and get on with your life. The best revenge is to live well so make sure you take good care of yourself . The kids have nothing to do with your divorce(they love you both) so be generous with your time and money when their welfare is at stake.
