Consequences of Shoplifting in New Jersey

My question involves criminal law for the state of: New jersey

Ok i'm 18 and was caught shoplifting from Walgreens and now i have a court date in a month. I've been researching what to do and what might help. So far i learned that i should plead not guilty and get a pd. i have no money for a lawyer because i only work part time so thats not an option. I want to ask about a diversion program to lessen the charge. Also i have no priors. Do you think i should plead guilty and just take whatever the judge gives me? If i do plead guilty, will i get any jail time? I know im going to have to pay fines but im not really concerned with money. Also the item was $25. If i plead not guilty how do i get a public defender? How much is it approximately? Will i have to pay for it right there and then? If i do have to pay for it on the spot, what will happen if i dont have enough money or any at all? Is it possible to have this expunged if i plead not guilty? Sorry for all of the questions but i have a month and im trying to prepare the best way i can.

As you can tell from the gazillion other threads you have surely read that ask essentially the same question, no, we don't think that you should simply plead guilty without figuring out if you can get diversion, a deferral, or a reduced charge. Read some of those threads, as your questions have been answered here countless times, then talk to your lawyer.

Thanks but I still need answers to the other questions. Also when I was arrested I was read my rights. I don't know if that's relevant or not but I just thought I should throw it in there
