Rialto starting player and initial order on Doge track
I found a copy of the English rules, and point 11 reads of the setup reads as follows:


  Beginning with the player to the right of the starting player and in counter-clockwise order, each player puts one counter on the first space of the Doge track.See below for details on the Doge track.


This would produce the opposite order of yours.

BoardGameGeek has a file titled "Official Czech Rules with corrections." Step 11 of that document reads as follows:


  Postupně od hráče po pravici začínajícího hráče a dále
  proti směru hodinových ručiček umístěte své označovací kameny
  na počáteční pole stupnice vlivu dóžete (více o stupnici vlivu dóžete
  najdete níže na této straně).


The quoted passage is in red, which has been used to identify the corrections. 

This matches the the text of the English rules I quoted above.
