Can I just show up to court and be heard that day without turning myself in on a 1st violation of probation?

The judge could potentially take you into custody (as opposed to releasing you on O.R. pending the PV hearing. Some attorneys do offer payment plans. It may be worth consulting with a few in your area.

Take any papers you have to a competent local defense attorney and discuss your matter. In my experience, probation violations do not require a separate bond. They are generally show causes directing you to appear on a certain date (at least in my experience). Although the defendant often has to be processed (finger printed, etc.) necessitating reporting to jail for a short time within a short time of being served. Your case or court may be different but I would doubt it.

maybe. It depends on whether you have a good provbation record. What is the PV about? Are you in GS court or Circuit court. Both places you eill be appointed a lawyer. If you had one last time, I'd ask them if they could go with you when you turn yourself in to argue you should be released on your own recognizance. At the very least bring any documnets that might help you in your defense of the PV.
