A half rope and a double rope are describing the same thing. The '1/2' symbol on the end of the rope denotes that the rope is a double rope, i.e. that it is not designed to be used by itself for climbing purposes.

Now then, a double rope is a system wherein both ropes are not required to be clipped into the same pieces of protection. For instance, if a route wanders between two separate crack systems and you are using both cracks to place pro into, you can clip one rope into all the pieces in one crack and the other rope into all the pieces in the other crack. This system will help tremendously in minimizing rope drag throughout the route. A good belay is also necessary to keep feeding the separate ropes indepently of each other.

A twin rope is a system where two separate ropes are clipped into every piece of protection. So, every piece of pro along the route should have both ropes clipped to it.

A couple advantages to either of these systems are the ability to rap twice as far as you could on a single rope and extra redundancy. If one rope gets damaged somehow, at least it is not your only lifeline. I have heard that the redundancy is one reason they are popular with ice climbers who like to combine sharp metal objects that they swing with a lot of speed and force with soft nylon ropes which are prone to being damaged by said metal objects.

I won't get into the questions where I have little practical experience such as who makes good double ropes and which diameters to get.
