So, I am going with your second suggestion (see below) but I would love 
to hear your outstream.write() side-track!


import os

with open(os.path.splitext(bpy.data.filepath)[0] + ".txt", "w") as outstream:

    plane = bpy.data.objects["Plane"]

    print("Plane rotation X:",plane.rotation_euler[0], file=outstream)

    print("Plane rotation Y:",plane.rotation_euler[1], file=outstream)

    print("Plane rotation Z:",plane.rotation_euler[2], file=outstream)

    print("Focal length:", bpy.context.object.data.lens, file=outstream)

    and so on...
