I need a 72 Tiffen 812 filter for my:
Nikon 24-85 f/2.8-4.0D IF Autofocus lens.
I see that a "wide angle" version of the
filter is available at considerably higher
price. Is this required? What are its
advantages?


Can't answer the "required" part, but i'd guess with a 24mm wide end it
would help. The WA filter simply has a very thin profile, meaning the
ordinarily thick metal ring is rather thinner. There is less chance of the
metal ring intruding on the corners of your frame, commonly referred to as
vignetting.
