The problem is that the numbering for the sections (subsections, subsubsections) is restarting at each unnumbered chapter. Then, the section numbers are no longer unique. The numbers are used to construct anchor names, which must be unique.
Package hyperref already uses \theH<counter> if available to get a unique
number for \the<counter>. The problem can be fixed by defining \theHchapter for the unnumbered chapters, e.g.:
\chapter*{Premiere chapitre}
\def\theHchapter{1}
...
\chapter*{Deuxième chapitre}
\def\theHchapter{2}
...
LaTeX expands the options for a package in a hard way that might break arbitrary TeX code as given in the text for the information entries.
Therefore, they should be given after loading the package in \hypersetup. Also pdfencoding=auto or pdfencoding=unicode is recommended to enable Unicode in the bookmarks and PDF information entries.
\usepackage[pdfencoding=auto, ...]{hyperref}
\hypersetup{
pdftitle={...},
pdfauthor={...},
% ...
}
Package geometry is specified several times. Then, use it and remove the low level stuff \special{papersize=...} (is done by geometry with the correct driver). Also, the settings \textwidth=..., ... can be replaced by options.
% More or less right after \documentclass, when
% the package is loaded the first time:
\usepackage[
includefootheight,
headheight=20pt,
footskip=22pt,
% ...
]{geometry}

I usually do this:
This uses the title defined by the
\titlecommand but you can use something else (then the\makeatletterand\makeatotherare not needed).
