Outstanding pictures, I wish everyone would post that type of detail and that many pictures.
BCRider gave good information, I ditto his and others.
Don't replace the cables but if you feel a drag, then removing the cables, cleaning them up with steel wool, putting some lubricant on them may help but you may have a groove in the inside plastic/teflon coating of the housing that's causing a drag. Cables are cheap, maybe $3, housing $1/foot needed.
