Internal rear brake cable routing.

Internal cable routing on top cable currently has a straw like cable guide sticking through each end. Am I right in thinking that I thread the inner cable through this first, remove the guide and then thread the outer over the top of the inner so that the outer goes all the way from the the brake caliper to the shifters through the frame.
Frame is a Dedacciai Nerissimo.
Also should I put any lube on brake cables ? Installing Chorus 11 speed. Instructions say derailleur outers are pre lubricated but it doesn't say anything about the brake outers.
