Recently arrest from shoplifting. 2 priors both over 20 years ago what am I facing when I go to court?

Very difficult to answer about what you are facing. Depends on the value of items stolen, facts of case, what your priors were for, and other factors. Potential for jail time or possibly just probation if a lesser amount. If you don't have a local lawyer you should hire one to discuss the case with the prosecuting attorney.
