What is the rule of the "key number (key_nb)" parameter
    in such files and in the commands (if it uses always these files, it
    does not need any number ?!?)

Each file holds four keys.  That's what the key number refers to.

  b) In order to do a INT/EXT AUTHENTICATE for a DES key, for example,
     what should I take as initial parameters for the algorythm
     (the IVs) ?

IV should be all zero, if there are no bugs in the card.
