Generally your slide set will start with something like

This enables special page size and margins that are useful for creating slides. It also creates a page break after each section (there may be other page breaks if you have more material than will fit on one slide). Of course you can always add more page breaks by using
<<newpage: >>
construct.
The moretexpreamble stuff is direct LaTeX code that allows you fine control over headers, footers, and the background of your slides. Especially the overlay feature is great for getting the "corporate look" to your slides. If you do not understand what it does, you need to ask some LaTeX expert. One caveat: the .pdf files that you might use in includegraphics are relative to the tex/ directory.
If you need to get just one or two more lines on page, you may find
< <tex: \enlargethispage*{\baselineskip}> >
useful.
In slide mode, the sections and subsections are not numbered. If you want numbering, you should simply add the numbers manually.
You can include images and figures in your slides in a normal way. However, at times it may be useful to omit the legend from the figures. You can do this by supplying "0" (zero) as the legend.
To print the slides, reorder pages (mpage -j flags are buggy)
pstops 4:2,3,0,1 /tmp/foo.ps /tmp/0.ps mpage -4 /tmp/0.ps | nc printer-ip-address 9100
The tricky part is getting the landscape slides ordered so they read naturally while most 4-up printing software (like mpage(1)) are geared towards portrait printing. If you print one, or even two, slides per page, this is not likely to be a problem. "Natural" two sided printing is left as an exercise to the reader.
