Needing to find out how to go about changing titles, assets out of my mother's name into mine & also what is the time frame needed to get paperwork do

You need to consult with an Elder Law attorney.  I'm in New Jersey and don't know California law.  However, most states has rules that prevent you from transferring a person's assets out of their name, and then asking for assistance with medical costs.  In New Jersey there is a five year look back rule - anything transferred within five years of applying for Medicaid can make the applicant ineligible to receive benefits - in other words there is a penalty.  You are going to want to proceed with caution.
