Cheese has salt for a couple of reasons. In many cases, it would taste funny without it. Salt is also a natural preservative, and is used as such particularly in cultures with warmer climates. Salt can also be used to inhibit, or in some cases to kill, the bacteria whose biological processes actually create the cheese, once a certain stage in the cheesemaking process has been reached.

It's cured and stored in its own salty whey brine.
The bread is made by using both sugar and salt. However the amount of the sugar or salt used is differently depending on the people who make. For example the french bread is made salty as people in french prefer a salty taste
It depends on the recipe, but probably not. Goat cheese is more delicate flavored and not as salty. It has a different texture, too. Feta is chunky, whereas goat cheese is more crumbly. If all you're doing is crumbling it into a salad, it's probably OK (but remember that feta is much sharper tasting). But if cooking is involved, I don't think it would work well.
