Before the cable and housing is replaced look at the original set up for any possibl;e changes with the new. The imaged housing damage is likely from rubbing against a tire or some other thing. Avoiding that again is a good goal. By changing the housing loop's length one can affect where the housing runs and whether it rubs on something (and check with the steering at 90*, not just with the bars point straight ahead).
Indexed housing wants a more controlled cutting method that the tight spiral brake housing needs. A Dremel tool with a cut off disk works well but most will use a "proper" housing cutter. This is why many home mechanics will have the LBS do the indexed housing cutting, saving the cost of the special cutter that won't get used at home very often. If you do this make sure your housing length needs are well determined before going to the LBS.
While you are installing the inner cable into the shifter take the time to lube the shifter internals. Andy
