Nothing wrong with the stock system as long as you don't expect brakes like you have on todays cars.
Parts for the Cdn2 are pretty standard jeep stuff. Right off, order a master cylinder, two 3/4 wheel cylinders and two 1" cylinders. There will also be a total of 4 flex lines, if you are keeping the jeep for the long term, or if the lines are showing their age, you will want to replace those as well. Sometimes the little "S" lines on the front are beyond salvage, although with a bit of ingenuity they can be disassembled without twisting them apart.
In all likelihood the drums are scored or warped. You can have them turned, but new ones are not that pricey. The shoes themselves can possibly be cleaned if they are oil soaked, or you can replace with new.
The Cdn two brakes were a fairly simple setup, and were not what is known as "self energizing". That feature was on the Cdn3 series. So when you have installed all those parts, and set up the brakes as best you can, don't be surprised if they won't lock up on demand. More likely the braking will be like coasting to a stop for the first 50 to 100 miles until the shoes really set in to the drums. Until they are, you may only have a portion of the friction material contacting the drums. This can be overcome by having the shoes arced into the drums, or time can do it for you.
While you are in the rear axle area, don't forget that the bearings in there are manually packed. There is an important seal on the inside area of the axle housing which should prevent oil from making it to the bearings.
