The letter behind the number refers to the durometer "hardness" of the wheel. In the case of the wheel in question, it must be a dual durometer wheel, meaning the core is harder than the outer part of the wheel.

A haze filter, typically an 81A or 81B Wratten-type filter is used to cut down the amount of ultraviolet light entering the camera's optics. You can use this instead of a clear glass filter to protect the front element of your camera lens. There are two types of polarizing filters - linear and circular. Depending on your type of camera (film versus digital), you may need to use a circular polarizer to be able to see through the lens system. Polarizers cut down the amount of light entering the lens by acting like a set of Venetian blinds and letting light only come in as a single plane. There is more information on polarizing filters in the question In photography what does a polarizing filter do?
