1. Cable looks ok, just watch it. That is where the cable is going over the "peak" of your cam and is normal.
2. W/B is fine, Should be bigger than you arrow.
3.Looks like either your knocking point or your restmight be out of tune, but you can't really say that by looking at a picture. Take it to a bow shop, not Bass pro, and have them tune it. It is well worth the little charge to have a properly tuned bow and get the best out of it.
