I just posted the code for a \Tabular environment which solves both
your problems with the size of the table (it is automatically split
across pages) and with footnotes.

I am reposting the code here because I had forgotten to skip
\doublerulesep between two consecutive \hline.

%
%  This file defines a \Tabular environment which is essentially
%  similar to the \tabular environment but is able to handle very
%  large tables which have to be split across pages.
%
%  The major distinction is that \Tabular doesn't take an optional
%  argument.  It behaves much like \begin{tabular*}{\linewidth} with
%  \Tabularleftskip and \Tabularrightskip used as the stretchable glue
%  on either side.  Also, instead of contributing the table as a large
%  box, it performs a \unvbox so that individual rows are contributed
%  instead and page breaks can occur between them.
%
%              \begin{Tabular}{...} ... \end{Tabular}
%
%  has essentially the same effect as:
%
%  \begin{center}\begin{tabular}{...} ... \end{tabular}\end{center}
%
%  but may be split across pages.
%
%      {\Tabularleftskip  = 0pt
%       \Tabularrightskip = 0pt
%       \begin{Tabular}{@{}l@{\extracolsep{\fill}}cr@{}}
%           ...
%       \end{Tabular}}
%
%  will produce a 3 column table with the left column flushed left,
%  the right column flushed right, and equal spacing between the
%  columns.

%  \hline is redefined to output 2 lines one on top of the other, with
%  a slightly more encouraging \pagebreak than between normal rows.
%  Thus, if a page break must occur, there will a line at the bottom,
%  and it will be repeated at the top of the next page too.  This is
%  visually much more appealing.
