I'm not a lawyer, and nothing I write is legal advice.
> even though no one got hurt
It sounds like you committed multiple crimes, regardless of whether anyone got hurt. Where is there any room for you to argue against the charges?
Your public defender might not be an expensive "good" lawyer, but this is a clear-cut situation. Your options are to:
1) take advice from a bunch of random people on the internet
2) take a lawyer's advice
My suggestion is go with #2, no matter how "bad" that lawyer might be. S/he certainly has more experience (and knowledge of the situation) than pretty much anyone on HN. It's kinda weird that you ended up here to ask for advice at all...
