What are the best procedures to eliminate Barrel Distortion (or
Pincushion
distortion), Chromatic Aberration and Parallax?
What do you mean by parallax? Traditionally, it refers to the fact the view as seen through a non-TTL viewfinder is not the same as the image on film, especially for close-ups, but there’s not much you can do about that after the fact.
Buying a proper lens would be the first one
All lenses distort.
Then there is a plugin (did I say plugin?) called LensDoc. http://www.andromeda.com/info/lensdoc.html that takes care of most barrels and pincushions.
Debarrelizer is much easier to use and cheaper:

Debarrelizer also helps with some common forms of chromatic aberration. Other plug-ins can be found via Google.
