While the quick soak or overnight soak will shorten the cooking time, beans will eventually cook. The presoaks just shorten the time.
Salt does not affect the cooking except for flavor--it is better to salt while cooking so the salt is incorporated into the bean.
Age does matter as many have mentioned. Buy your beans where there is a turnover of product.
AND I love my pressure cooker for beans!!!!
