These lines set the origin (ref pt) and scale:
session.location.setrefgeo(47.57917,-122.13232,2.00000)
session.location.refscale = 150.0

Yes. Set emane_event_monitor=True in /etc/core/core.conf if you want to
subscribe to EMANE location events; emane_event_monitor=False if you want to
generate them using the X,Y location of nodes.

There is no pathloss event GUI; there is a Comm Effect Controller GUI (which
would be option #4), only works with the Comm Effect EMANE model. There are
emaneeventpathloss Python bindings that make it easy to generate pathloss
events from a Python script.

With pathloss events, location doesn't matter.

You can start the Python script from the GUI and the GUI will connect to the
running session; see "Execute Python script" under the File Menu:
http://pf.itd.nrl.navy.mil/core/core-html/usage.html#file-menu
Also, you can start a Python script with this syntax:
# start cored as normal
sudo cored
# tell cored to execute a script and add the session to the active session
list
cored -e /path/to/mycorescript.py
# run the script, passing it command-line arguments
cored -e "/path/to/mycorescript.py -n 10"
The GUI can later connect to scripts started this way using the "Session" >
"Change sessions..." menu item.
