Is the only way to take care of an old warrant turning oneself in?

I am interested in whether a person can hire an attorney for limited assistance representation to help clear up a warrant that is over a decade old in another state (a warrant in which said person was specifically identified as having nothing to do with the crime in question and retains the documentation to prove as much). This warrant could have been served a few times during minor traffic violation stops over the years in the neighboring state which is very close by, about an hour and a half drive and was it was not. It is said to be non extraditable. If going in to be processed for a warrant is the only option, do they have a legal right to find out exactly what the charges are against them prior to doing so? Can they contact a bondsman and find out what it will cost to be bailed out so they can turn themselves in then go home afterwards? Of course showing up at any all future court dates. Thank you.
