These sequences are defined in notebook2e.sty.  Are you sure these
files are in a location that is searched by your TeX installation?
Did you remember to update the filename search database that is used
by your implementation of TeX?

As I mentioned above, there is no clean analog of \[AlignmentMarker]
in TeX.  In LaTeX 2e, one may use the eqnarray environment to control
layout of equations.  The closest thing that you can do in a
Mathematica notebook is to use grid box structures.  Paste this Cell[]
expression into a notebook and click on "Yes" on the resulting dialog
box to see what I am talking about.

Cell[BoxData[GridBox[{
        {
          RowBox[{"a", "+", "b"}], "=", "c"},
        {
          RowBox[{"c", "+", "d"}], "=", "e"}
        }]], "Input"]


This will convert to:

\dispSFinmath{
\MathBegin{MathArray}[c]{ccc}
	a+b&=&c \\
	c+d&=&e 
  \MathEnd{MathArray}
}

The notebook that is converted by TeXSave[] is actually a preprocessed
version supplied by the front end; automatic numbering objects
(CounterBox[]) are resolved to literal values.  This is akin to
performing the front end menu command Input -> Convert Automatic
Objects to Literal before invoking TeXSave[].  Unfortunately, the
front end does not properly resolve the value of options with
CounterBox[] objects.  This hits automatically numbered equation
styles, which embed CounterBox[] objects in the value of the option
CellFrameLabel.

That might have to do with some troubles that DVIPS has with partially
subsetting the Type 1 Math fonts.  If you run into this problem, try
including the command line flag -j0 to force complete embedding of the
fonts.  This will result in larger PostScript output files, but the
glyphs in the file will be rendered properly on any PostScript
interpreting device.
