Converting to Reform Judaism?

My father was Jewish, and my mother was Catholic, since my parents were divorced at an early age and my mom had custody over me, I was forced into Catholicism although it is never truly what I believed in. I was also forced into being confirmed. Now I'm old enough to make my own decisions and I've decided that I want to be Jewish... Reform to be exact. I have a meeting with a Rabbi today and she's going to walk me through the conversion process. I was told that reform Judiasm, being very liberal will except me as birthright through mt father's side of the family as long as I can show them I'm serious. Others have told me that I need to do years of Hebrew School before I'll be considered, I think that that's only with orthodox, or more conservative forms of the religion. Has anyone else gone through this process? What can I expect? Also, someday even if it is down the line, I would like to have a bar-mitzvah. Any insight?
