No need to use putValue. When you use getValue you are getting a
reference to the object.

No. getValue simply returns a handle to the object so that you can
access it.

Yes. Each time an object is put into the session the listeners get
kicked as a put of an object with the same name as one allready in the
session requires that the previous object gets unbound and the new
object gets bound.
No. valueUnbound only gets called when the object is removed from the
session, either by removeObject or a replacement.
