Jon,

First of all I think you misunderstand the fontspec option cm-default. 
You've overriden it by specifying \setmainfont.

Here is what I did to achieve what you want. Note that I needed to 
change the fonts since I only have Type1 versions of Frank Ruehl and David.

\documentclass[12pt]{book}
\usepackage{fontspec}
\usepackage{xunicode,xltxtra}
\usepackage{bidi}
\newfontfamily\ezra[Script=Hebrew]{Ezra SIL}
\newfontfamily\adobeh[Script=Hebrew,Scale=0.92]{Adobe Hebrew}
\begin{document}

%%A
This text is in Latin Modern because no font was specified.

%%B
{\setRL\ezra
עברית : Hebrew stuff in Ezra in right to left mode

\adobeh עברית : Hebrew stuff in Adobe Hebrew in right to left
}
%%C

\setLR This is again left to right with default roman font.

%You can also simplify the above by defining an Hebrew environment:
\begin{verbatim}
\newenvironment{Hebrew}{\setRL\ezra}{\unsetRL}
\end{verbatim}

\newenvironment{Hebrew}{\setRL\ezra}{\unsetRL}

\begin{Hebrew}
עברית
\end{Hebrew}

English
\end{document}

See the attached pdf file.

François
