DSL only uses two wies- a single twisted pair. At the female phone receptacle find out which connections lead to the center two gold pins and use those. Again be consistent with the colors. You can hook up a second pair to the two outside pins just in case you want to use a two line phone anywhere.
You'll only need the ethernet jacks/ receptacles if you split the DSL modem signal with a router to serve other computers. You can use the CAT5 wiring, but it needs to be a separate sytem from the phone system.
