My question involves criminal law for the state of: California

I live in Northridge, California, San Fernando Valley and I was just wondering what are the possible punishments for PC petty theft, code 484, for taking rolls of toilet paper from a university bathroom? And if the punishment is a fine what is the most likely cost of the fine?

This is my first offense. And it was stupid on my part. I just thought it was just toilet paper and it was hanging around and it's not a big deal. I knew it was wrong on some level, but it was just toilet paper and I, like an idiot, took some. I wanted to save money and I tried to take an economic short cut.

I have a set court date. Also, I was wondering is there any way I could get this off my personal record? I know this can hurt me for future employment. Do they automatically give me a public defender when I appear in court or do I have to ask for one?
