Here's what I use.  For the handouts my .tex file has

    \setlength{\partopsep}{2pt plus 10pt minus 1pt}
    \setlength{\parindent}{0pt}

    \newcounter{fig}
    \newcommand{\mkslide}[1]{%
    \addtocounter{fig}{1}
    \pagebreak[3]
    \input{#1}
    \begin{center}
    \fbox{\em Slide {\thefig}} \\
    \rule{\textwidth}{1pt}
    \end{center}
    \pagebreak[3]
    }

and for each slide I do

    \mkslide{who}

where who.tex is a file to suck in.

For the slides the macro for \mkslide is simply.

\newcommand{\mkslide}[1]{
\begin{slide}{}
\input{#1}
\end{slide}
}

So I have two files, paper.tex and slides.tex where paper.tex uses the
first version of \mkslide, and slides.tex the second version.  Both
input the file slide_files.tex which has a \mkslide for each slide
(one file for each slide) but paper.tex uses \input{slide_files} while
slides.tex uses \blackandwhite{slide_files}.  Also, paper.tex uses
\documentstyle{article} and slides.tex uses \documentstyle{slides}.

When you add, rearrange, delete, etc. slides you only need to fiddle
with slide_files.tex, not paper.tex or slides.tex.
