This is not the answer you are wanting to hear. But, from what you are describing your place is long overdue for a rewire. The lightning strike was a nice wake up call, enabling you to find the bad "fix" in the wall. Can you get in the attic to inspect what is there?
I would do whatever you can to replace all of the old cloth covered stuff. It's started to deteriorate and I'm afraid you will keep on finding things like the splice.
A tone and probe set will not really do what you want unless you kill the main breakers and all power to the house. Electrical wiring is often daisy chained and go to many places. Telephone wiring is usually one wire to each jack so the tone only goes to one location. Often times you can find the tone going all over the place. The circuit breaker finders work pretty well, as others have indicated. There are several different brands, all do the same thing. In order to label everything accurately you are going to have to plug a light or radio or whatever into each outlet and use phones or the little inexpensive walkie talkies and spend a day turning things on and off because each breaker/fuse may go to several places.
Bottom line is you have a potentially dangerous situation with all of that old wiring compounded by whatever previous tenants have done to it.
