These:
bpy.data.particles["ParticleSettings.001"].use_rotations = True
bpy.data.particles["ParticleSettings.001"].rotation_mode = 'NOR_TAN'
bpy.data.particles["ParticleSettings.001"].use_rotation_dupli = False # Locks particle rotation when rotating emiting object
were gleaned while testing the above.
