[XeTeX] font shapes not defined resulting in accents too high?

This is because babel has been designed with standard (La)TeX in mind: 
it assumes you are using fonts in either OT1 encoding (the 7-bit ASCII 
encoding of the original Computer Modern -- CM -- fonts) or T1 encoding 
(the 8-bit encoding, also known as Cork, of the European Computer 
Modern -- EC -- fonts), not fonts in Unicode encoding.

Hence, for maximum compatibility -- in standard (La)TeX sense -- it 
contains definitions such as (from french.ldf):

\ifLaTeX
\@namedef{captions\CurrentOption}{%
    \def\refname{R\'ef\'erences}%
    \def\abstractname{R\'esum\'e}%
    \def\bibname{Bibliographie}%
    \def\prefacename{Pr\'eface}%
    \def\chaptername{Chapitre}%
    \def\appendixname{Annexe}%
    \def\contentsname{Table des mati\`eres}%
    \def\listfigurename{Table des figures}%
    \def\listtablename{Liste des tableaux}%
    \def\indexname{Index}%
    \def\figurename{{\scshape Fig.}}%
    \def\tablename{{\scshape Tab.}}%
    \def\CaptionSeparator{\space\textendash\space}%
    \def\partname{\protect\@Fpt partie}%
    \def\@Fpt{{\ifcase\value{part}\or Premi\`ere\or Deuxi\`eme\or
    Troisi\`eme\or Quatri\`eme\or Cinqui\`eme\or Sixi\`eme\or
    Septi\`eme\or Huiti\`eme\or Neuvi\`eme\or Dixi\`eme\or Onzi\`eme\or
    Douzi\`eme\or Treizi\`eme\or Quatorzi\`eme\or Quinzi\`eme\or
    Seizi\`eme\or Dix-septi\`eme\or Dix-huiti\`eme\or Dix-neuvi\`eme\or
    Vingti\`eme\fi}\space\def\thepart{}}%
    \def\pagename{page}%
    \def\seename{{\emph{voir}}}%
    \def\alsoname{{\emph{voir aussi}}}%
    \def\enclname{P.~J. }%
    \def\ccname{Copie \`a }%
    \def\headtoname{}%
    \def\proofname{D\'emonstration}% for AMS-\LaTeX
    \def\glossaryname{Glossaire}%
    }
\fi

The problem is, commands such as \`e don't work well in XeTeX which is 
based on Unicode and expects è instead. Generally what I do (as I don't 
like Babel's defaults most of the time anyway) is redefinitions in the 
preamble, such as:

\AtBeginDocument{%
   \renewcommand{\contentsname}{Table des matières}}

or even better for my taste:

\AtBeginDocument{%
   \renewcommand{\contentsname}{Sommaire}}

As I am writing this I receive Ross' post which solves all these 
problems in a much more general and elegant way, so please regard my 
post as complementary information only.

The occurence of \`e makes TeX look for the font Adobe Garamond Pro in 
OT1 encoding, but this font has only been defined in U encoding. This 
message should disappear with the above redefinitions.

There is no slanted version of Adobe Garamond Pro defined. I don't know 
(not having the font myself) whether this version exists. If not, you 
can use in the preamble:

> \DeclareFontShape{U}{AdobeGaramondPro}{m}{sl}%
>      {<-> ssub * AdobeGaramondPro/m/it}{}

Hope this helps,
