No questions are dumb!
A few comments
1. Each of these segments (I'm assuming you mean C10, C11, and C12, not C22 which doesn't exist) are a REALLY long way and not possible to do in a single day (if that is your plan) without transport assists. As others noted in previous threads it is not the distance, it is the altitude gain that is super challenging and really slows you down.
2. I don't think you will see many Via Alpina signs, I've done the entire route (Sargans to Montreux) and don't recall seeing many. Rather, you should be looking for the routes to the villages along the way. So, for example, for Grindelwald to Lauterbrunnen you can start at the railway station, follow the signs to Alpiglen where you catch the famous Eiger Trail up to Eigergletscher station. From there down to Kleine Scheidegg (which you can see from Eigergletscher) then to Wengneralp, Wengen, Lauterbrunnen.These segments are highly traveled therefore very well marked. C11 and C12 are much wilder and take you over the two most challenging peaks in the region. You will need topo maps which you can buy in Grindelwald or at Foto Fritz in Wengen once you get there.
3. As a single you may not need to book huts ahead but start looking early before you are exhausted. For c11 there is not much of anything between Rotstocke Hütte and Griesalp which is tough going. (I believe Obere Dürreberg is very small and may not even be open in Oct.)
