You are right. I tried a 150 pages Notebook to convert into TeX and  
it looked really ugly.
But there is someting, that can be done: I wrote a small file (named  
it MMaInput.tex) which looks like this

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{bm,parskip}
\newif\ifInMMaBold
\renewcommand{\pmb}[1]{\InMMaBoldtrue\bm{{#1}}\InMMaBoldfalse}
\let\urtext\text
\renewcommand{\text}[1]{%
   \ifInMMaBold
     \urtext{\textbf{#1}}
   \else
     \urtext{#1}
   \fi
}
\let\urgrave\grave
\renewcommand{\grave}{\,\urgrave\,}

It has to be imported after the \usepackage commands in the TeX file:
\input{MMaInput}

This way I get all MMa input-lines in non ugly bold. Math is typeset  
bold because of the use of \bm, which replaces the ugly \pmb of  
amsmath. The \text{...} stuff inside these lines is made bold too  
with the \renewcommand of \text, which takes care of beeing inside  
bold stuff.
For me the backticks were to tight to be visible, so I did a  
\renewcommand of \grave too.

Loading the parskip package avoids indenting new paragraphs and adds  
a blank line instead. This makes the output look better in this case.  
In "normal" LaTeX files I usually don't use this.

Remark to \unicode:
In my big file there were only calls of \unicode{0009}. In the  
notebook these were tabs, which TeX doesn't honor. A workaround is to  
change the unicode command to:
\newcommand{\unicode}[1]{\quad\quad\quad}.

This doesn't look pretty, because the columns will be ragged, but  
better then no space at all.

My conclusion is: It's worse then in older Versions of Mathematica. I  
think it's best to print the notebook to a PDF-File.
