If you are really located in California it may be impossible for you get a job within the school district. I don't know a lot about different districts so maybe you are in the one that is hiring.
My advice to you is to find out what the job market looks like before you jump in with additional training. Without a teaching certificate you cannot teach and 12 year old computer skills are worthless. One of my many hats is teaching people in my office new platforms. Things change yearly, five years is too long, twelve years....
So find out what is out there and what skills are needed. Go from there.
