Car is a good bet and generally the parking isn't especially miserable though on-street parking is often metered. Navigating the green can be a bit of a headache at times and depending on where you want to go, but it's nothing to lose sleep over. A range of exits off of highway 287 allow quick and easy access to different parts of the city.
The Morristown train station is generally well serviced by NJ Transit, where one can commute between New York City Penn Station in about an hour. http://www.njtransit.com/
Most places in the heart of the city (the green) are easily accessible by walking. If you arrive by train you'll probably have to call for a taxi for going anywhere beyond the immediate area. Walking will serve you well otherwise. You can call ahead for a taxi 973-539-2500 [], 973 998 8863 [] or for a car service 
If you do want to take transit, the #871, #872, #873, #874, & #875 run by NJ Transit offer some service to the surrounding areas, though it runs rather infrequently.
