New discovery for anyone interested: You can just enter the SERVICE_NAME / GLOBAL_NAME (the one used in tnsnames) into the "database" field and leave the host and port blank.
QGIS will then connect automagically to the server (it populates that stuff from the tnsnames file). This seems like the optimal way to use it.
