The best wat would be to create parameters in your python script. Examples here : http://wiki.ros.org/rospy/Overview/Parameter%20Server (Make them private with ~)

For example in my node I have :

self.target_frame = rospy.get_param("~target_frame", "map")

And I can start it like in in my launchfile :

<node if="$(arg use_radar)" pkg="aw_platform" type="radar_relay.py" name="radar_relay" output="screen">
    <param name="target_frame" value="test" />
</node>

This method is very good because it allows you to use the parameter server to set your parameters also and load your parameters from a yaml file for example.
