Hmmmm, someone erased your name??
Sounds like a job for the mods.
Any way, if you have balloon framing you need to install blocking at the basement to seal the basement up to the attic connection.
This will help with air going up through the chases in the exterior walls and when you insulate the blown in does not filter into the basement.
As for the electrical, I would have an electrician or three give you advice on your system. You have no updated stuff and no ground wiring.
And you CANNOT put insulation in a wall with knob and tube...then you will burn the house down.
And the insurance guys don't care for it either.
Let us know if we can scare you anymore.
No home is perfect, take it slow and just do what you can as you can.
