yeah--you can work and do whatever you want--just stay away from your counties radius--call them to find out what it is--they will tell you, it is ok to ask them--
I have warrants in other states but they are misdemeanors and so it doesn't matter--I have even been arrrested where I live now and the other stuff has not been an issue. Only felonies travel nation wide.

I say leave and if your g-friend is old enough to take with you then take her--but be realistic and know that almost definitely you will not be with her forever anyway--take it from my own experience--I have done a lot for girls in my day and not one of them am I still with--you grow and learn

but about the probation -- dont worry about it and just leave--at least as an adult it doesnt matter--I have never been in trouble when I was underage
ps--if you collect blotter sheets like in your avatar I have lots of them that I sell
