Does my marijuana poss. in Pa make my jersey poss. my 2nd? Or 1st? Should I definitely get a lawyer?

I was arrested and charged with having under 50 g (1 gram) of marijuana (disorderly persons). I took the rap for a buddy a few years ago in Pa and was charged with possession of marijuana, paraph., and underage. Since it happened in Pa, will this count as possession offense #2? Or 1? And did I read #2 in jersey is a Felony even if its only a disorderly persons offense? I was cited on Open Container, found to have a warrant from unpaid wildwood fines, and while being arrested for that, found with it in my back pocket. I got a continuance and pled not guilty. My boss can prob get me a local lawyer, and seems confident a deal can be reached. I am sort of inexperienced as pertains to the laws/court (insert joke here), is this something I should DEFINITELY get a lawyer for? What am I lookin at penalty wise?
