Welll first you need to go to the office of the Catholic Church in your city or community, ask for the preparation to get your baptism ( courses or classes) then you finish your preparation they set the date, then you need a witness or witnesses (someone who is already baptized and need to be confirmed in the Catholic religion or a couple that is married under the Catholic Sacrament).
You should visit your local Catholic Church. Ask about the RICA process. You are heading on right direction.
I would see about the Adult Catechism program.
