Hi,
A few quick fixes:

1.  There is a bug in rlbabel.def that causes  problems when using
underline in equations inside hebrew sections (note it was  OK in 
but not inside ).
Fix: In Hebrew.dtx (line ~1847)
change from
\def\underline#1{\@@@underline{\if@rl\R{#1}\else #1\fi}}
to
\def\underline#1{\@@@underline{\ifmmode#1\else\if@rl\R{#1}\else #1\fi\fi}}

2.  Defining the letter name "sin" conflicts with \TeX's math  mode sine.
Fix: in hebrew.fdd (line ~283) change
from
%<+LHEenc>\let\sin=\shin
to
%<+LHEenc>\let\HEBsin=\shin

3. Add a note to the docomuntation regarding the use of the oldjaf10.mf
font:

%
% \item \textbf{oldjaf10.mf}
%    This font, used for |\emph| was not identifies as slanted. As a
%    result, a nested |\emph| had no effect (\LaTeX checks if the current
%    font is slanted or not, and toggles normal and slanted font)
%    A \emph{font\_slant} parameter should be added to \emph{oldjaf10.mf},
%    it should look like:
%    \begin{verbatim}
%      font_slant            0.001pt#; %%#TK added to identify as slanted
%      font_normal_space     3.30033pt#;
%      font_normal_stretch   0.15em#;
%      font_normal_shrink    0.1em#;
%      font_x_height         3.30033pt#;
%    \end{verbatim}
%  The slant value is very small to ensure no influence on appearance.

These are the fixes that has to do with Babel & Hebrew alone.
I've found them about a year ago, when I prepared a distribution for
the faculty (you can find it in http://www.ee.technion.ac.il/~tomer/TeX/).
As far as I remember I emailed them to Boris at the time.

There are many other patches/fixes that are needed if you want to use the
Hebrew support AND hyperref, but I haven't updated it in the
last half year or so, so it may not work with current versions of hyperref.
I'll update it "sometime", when I have the time.

Tomer
