Installation Help

I am trying to install a Dimmer 2 on a hall light with two toggle switches, one at either end of the hall. The circuit is confusing me and I don't know if any of the diagrams I've been able to find online are right for my setup.

 

The switch in question is on the right of the images attached. The other switch is for the living room lights, so you can more or less ignore that one. The red wire you can see in the back of the box goes to the switch at the other end of the hall. I can also tell you from having recently changed the light fixture, there are two wires going into the fixture, again not sure that matters exactly. I assume the white bundle at the bottom are my neutrals?

 

These diagrams are what I've found for the three-way type switch setup:

 Do any of those make sense for the circuit I"m dealing with? Or is there somewhere else I can find a wiring diagram? 

 

Also, when the wiring diagram shows a small little connection to the "N" point, does that mean I need to jumper from the "Sx" with a short piece of wire or something?
