DO NOT remove the both inner wires and the housings from the frame; leave one or the other to act as a guide for the new parts, I'd suggest leaving the wires. If you pull both out you will have to figure a way to route through the frame again, which will really suck. Don't ask how I learned this. Again, have a plan before you start, don't leave yourself "stranded".
You will also need to prepare the housing ends after you cut them.

Yeah, pulling the housing off of the wiring was my wild guess on how to do it - clamp down one end of the wire and thread it through the other. Initial install of those things must be a chore - I could see how you could do it with a strong magnet but still.
I'd considered the Park Tool cutters for the actual cable, but it sounds like I need to pick up some stuff for the housing as well; thanks for the link.
This is a slow project that's just in the planning phase so it'll probably be months before I actually get to work - other things in the Bike Budget Queue must come first. Once I get a new chain breaker in (my old one is trash) I'll start the "pull apart and inspect" phase. Need to get a handle on the hubs - rims look fine from what I can tell, but I remember having to use copious degreaser on the rear hub once due to a sticking issue I never quite figured out.
