As long as you have no programs listening to these ports, you can disable all of them. Unless you are hosting something (webserver, game, etc), there is no need for any incoming ports to be open to the net on a router.

Here (http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers) is a port listing (the more "official" list is here (http://www.iana.org/assignments/port-numbers)).
