Parking permits for Middletown are issued by the clerk's office. You can apply for a permit at an auxiliary lot and will automatically be wait listed for the main lot. 732.615.2016 http://www.middletownnj.org
There is also a shuttle service that provides transportation from a few different lots to both the train station and the Belford ferry dock. It's called dock and roll. http://www.dockandrollshuttle.com/

Generally there is a waiting list for parking in the lot closest to the train but there is other parking options available. Hope that helps.
