Question #1

prototype has the benefit of monkey patching. As the first example shows, the function are added after-the-fact. You can continue this to add or replace any methods you need (though, with fair warning).

Defining objects like #2 is more along the lines of classic OOP. But, then again, monkey patching isn't allowed in all OOP languages.

Question #2

In your 3rd function, you don't even need the get and set functions -- name and age are public properties (the potential downside to {}).

var User = {
  name: "",
  age: 0
};

User.name = 'Bob';
User.age = 44;

console.log("User: " + User.name + ", Age: " + User.age);

When you create an object using {} (an object literal), {} is the constructor (varying on browser). But, essentially, no you can't use a constructor in this format.
