Stay in edit mode.  Select a bone by clicking on the portion between the circular endpoints.  You could also select it by selecting both of the endpoints.  Open the edit panel below the 3d window.  You should be able to find the name of the armatue object and the name of the bone selected (see image).  If you select all bones (a key) you will see the names of all of the bones.

The first bone created will be called "Bone" and the second one will be called "Bone.001".  The name of the object is probably "Armature".  Every type of object has an object name and a mesh/curve/armature name in the Link and Materials panel.  We're just worrying about the OB: one right now.  Remember these names so you can set up your vertex groups and the armature modifier later.

The first bone you created, the bottom bone, is the beginning of the chain of bones.  It is the parent of the top bone.  Next to the top bone you will see "child of" and a drop list that shows the name of the bottom bone.

You should probably look at the manual to see what the other buttons do.  The manual may or may not be up to date on these, I dont actually know.
