The ground wires should not be terminated on the neutral bus. They should be terminated on to the ground bus which should be located on the back wall of the distribution panel. The wires don't have to be pigtailed when inserted into the ground bus. More that one wire can go under the terminal screws if you are running out of room. Shut the panel off and remove any ground wires that are now under the neutral bus terminals and move them to the ground bus. Some panels use a lug for a ground bus. All ground wires into the lug and tighten. In a ground fault condition it is the ground wires that are connected to the ground potential that trip the breaker, not ground wires connected to neutrals. Be safe.

Your old wiring has 2 "hot" wires and a ground. Your new appliance needs 2 "hot" wires, a Neutral, and a ground. Please consult an electrician.
A 3 wired electrical fixture includes positive, negative and ground. The ground can be attached to one of the screws in the wall. In the case of the other wires, matching the colors, twisting and capping the wires together will handle the electrical installation.

If you don't have the wire then you just can't ground it. This should not be too much of a problem. Most light fixtures are not grounded and some don't even have ground wires.

Yes, the plastic in a wall outlet can over time get brittle. I recommend you replace any outlets and switches that are over 20 years old. I recommend you replace them and wire them by wrapping the wires around the screws and not by inserting the wires in the spring tension holes on the back of the outlets. An outlet that is subject to repeated plug ins and unplugging of a device should be replaced every 10 years.
In wall speaker wire is useful, as it hides the wires from sight. When a surround sound system is installed, it can lead to a number of unsightly wires appearing around the room. In wall wires hide this problem.
The simplest way is to put the wire there first, while the wall is not yet finished. Then you finish the wall. It is good practice to use plastic tubes for the electrical wires inside the wall. Using the tubes and the old wires, you can pull new wires through the tubes. Electricians use special metal wires to help with this.
