The CO/ALR is a receptacle designed for use with aluminum wire.
See - http://www.alwirerepair.com/serv02-view.htm
Pigtailing is the tying together of electric wires. I would not endorse it as a solution for your home, for the reasons shown here: http://www.alwirerepair.com/examples_of_burnt_wire_nuts.htm
Net/net, get a licensed electrician to correct your wiring connections.

I'm not sure what the abreviation means but I would guess copper/aluminum recepticle.
Here is a link that discusses them.

You didn't ask why they need to be changed, so I assume you understand the lower current capacity of aluminum wiring versus copper? My opinion is that aluminum wiring was mistake and has turned out to be a false saving in building construction.

The electric code differs with where u are. Aluminum is not a good solution. The metal will get hot and the clamp will loosen and the joint will heat more. I have found many ends melted off.
