The cloth covered wire I suggest you be very careful with it . if the insulation is brittle when you reconnect the wire it can break far down enough that you'll never get it to stop shorting out since the insulation will crumble in your hands If the wire sheathing is still pliable Then cut the very tips of the wire flush There should be a white and then a colored wire When you cut the tip of the wire flush You should be able to see what color it is could be black , red , however it can also be white too . You should get a tester and find which one is hot By testing power to ground Basically hold one probe to the metal box and touch the other probe to each wire When you get power That's your hot wire Hook it up the black wire on the new fixture . The other to white polarity is important While the fixture will work Bulbs tend to not last to long not even the LED but fluorescent lights or. CFL seem to be okay with it

Does not matter. It is AC. You can wire them sass backwards & they still work FOREVER. There should not be a ground wire.

With out a meter who knows. Blacks suppose to be hot. Suppose the key word there. If your gonna work on it hot I'd check with meter an still treat both wires like there hot. Why not just throw the breaker.

The black wire is hot, the white wire is neutral and the green wire is ground.
