Como posso formatar o índice (\printindex) de uma maneira específica?

Question

Se você quiser os números das páginas no índice, simplesmente não os remova com sua redefinição de \index. A formatação pode ser feita com algumas alterações Idx.iste algumas definições adicionais:

\RequirePackage{filecontents}
\begin{filecontents*}{Idx.ist}
headings_flag 1
heading_prefix "\\indexheading{"
heading_suffix "}"

delim_0 "\\hfill"

group_skip "\n"
preamble "\\begin{theindex}\\starttheindex"
postamble "\n\\stoptheindex\\end{theindex}"
\end{filecontents*}
\documentclass[8.5pt,% book does not know this option (but don't forget the comma!)
  twoside,% this is default
  openany,% so usually you do not need \let\cleardoublepage\clearpage
  a4paper]{book} 
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel} % use new spelling instead of old
\usepackage[utf8]{inputenc} 

%\usepackage[scaled]{uarial}% uarial is a very ugly mix of Arial and Helvetica 
\renewcommand{\familydefault}{\sfdefault}
\usepackage{multicol}

\usepackage{titlesec}

\usepackage{imakeidx} 


\usepackage{hyperref}

\makeindex[options=-s Idx.ist]

% If you do not want page numbers but, e.g. subsection numbers in the index:
%\LetLtxMacro\OldIndex\index
%\newcommand*{\indexpage}[2]{#1}
%\renewcommand{\index}[1]{\OldIndex{#1|indexpage{\thesubsection}}} 
\newcommand*{\indexheading}[1]{%
  \indexrule
  \textbf{#1}\par
  \nopagebreak
  \vskip-\baselineskip% go back to the heading line
}
\newcommand*{\indexrule}{%
  \par\nopagebreak
  \vskip-\ht\strutbox
  \hrulefill\par\pagebreak[3]
  \vskip -\baselineskip
  \hrulefill\par\nobreak
}
\newcommand*{\starttheindex}{\raggedcolumns}
\newcommand*{\stoptheindex}{\indexrule}
\makeatletter
\renewcommand*{\@idxitem}{\par\hangindent 2em\hskip 1.5em}% indent the entry
\makeatother

\begin{document}
\chapter{Test}
Irgendein Text.
\section{Eins}
Blablabla.
\subsection{Regeln}
\index{Ausland}
\index{Sieger}
\index{Spieler}
\index{Spielfeld}
\subsection{Beschäftigung}
\index{Beruf}
\index{Arbeit}
\vfill
\clearpage% should be used before \addcontentsline

\addcontentsline{toc}{chapter}{Stichwortverzeichnis}% the index is a chapter and becomes the font for chapter entries that is already bold
\renewcommand{\indexname}{Stichwortverzeichnis}
\fontsize{7.5pt}{0pt}
\printindex 

\end{document}

Se você remover a %frente de

\LetLtxMacro\OldIndex\index
\newcommand*{\indexpage}[2]{#1}
\renewcommand{\index}[1]{\OldIndex{#1|indexpage{\thesubsection}}}

você terá:

Para evitar quebras de coluna dentro de grupos, você pode adicionar um adicional \nopagebreakna definição de \@idxitem:

\RequirePackage{filecontents}
\begin{filecontents*}{Idx.ist}
headings_flag 1
heading_prefix "\\indexheading{"
heading_suffix "}"

delim_0 "\\hfill"

group_skip "\n"
preamble "\\begin{theindex}\\starttheindex"
postamble "\n\\stoptheindex\\end{theindex}"
\end{filecontents*}
\documentclass[8.5pt,% book does not know this option (but don't forget the comma!)
  twoside,% this is default
  openany,% so usually you do not need \let\cleardoublepage\clearpage
  a4paper]{book} 
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel} % use new spelling instead of old
\usepackage[utf8]{inputenc} 

%\usepackage[scaled]{uarial}% uarial is a very ugly mix of Arial and Helvetica 
\renewcommand{\familydefault}{\sfdefault}
\usepackage{multicol}

\usepackage{titlesec}

\usepackage{imakeidx} 


\usepackage{hyperref}

\makeindex[options=-s Idx.ist]

% If you do not want page numbers but, e.g. subsection numbers in the index:
%\LetLtxMacro\OldIndex\index
%\newcommand*{\indexpage}[2]{#1}
%\renewcommand{\index}[1]{\OldIndex{#1|indexpage{\thesubsection}}} 
\newcommand*{\indexheading}[1]{%
  \indexrule
  \textbf{#1}\par
  \nopagebreak
  \vskip-\baselineskip% go back to the heading line
}
\newcommand*{\indexrule}{%
  \par\nopagebreak
  \vskip-\ht\strutbox
  \hrulefill\par\pagebreak[3]
  \vskip -\baselineskip
  \hrulefill\par\nobreak
}
\newcommand*{\starttheindex}{\raggedcolumns}
\newcommand*{\stoptheindex}{\indexrule}
\makeatletter
\renewcommand*{\@idxitem}{\par\nopagebreak\hangindent 2em\hskip 1.5em}% indent the entry
\makeatother

\begin{document}
\chapter{Test}
Irgendein Text.
\section{Eins}
Blablabla.
\subsection{Regeln}
\index{Ausland}
\index{Sieger}
\index{Spieler}
\index{Spielfeld}
\subsection{Beschäftigung}
\index{Beruf}
\index{Arbeit}
\index{Test1}\index{Test2}\index{Test3}\index{Test4}\index{Test5}
\index{Test6}\index{Test7}\index{Test8}\index{Test9}\index{Test10}
\vfill
\clearpage% should be used before \addcontentsline

\addcontentsline{toc}{chapter}{Stichwortverzeichnis}% the index is a chapter and becomes the font for chapter entries that is already bold
\renewcommand{\indexname}{Stichwortverzeichnis}
\fontsize{7.5pt}{0pt}
\printindex 

\end{document}

Mas eu não recomendaria isso, porque você obterá colunas cheias demais se um grupo for maior que a altura da coluna.

Para alterar a distância vertical acima da regra, basta alterar a linha

  \vskip-\ht\strutbox

na definição de \indexrule, por exemplo,

\newcommand*{\indexrule}{%
  \par\nopagebreak
  \vskip\dp\strutbox\nopagebreak
  \hrulefill\par\pagebreak[3]
  \vskip -\baselineskip
  \hrulefill\par\nobreak
}

resultaria em

Observe que usei outra fonte, pois não tenho a feia URW-Arial instalada.

Você também deve dar uma olhada nas diversas notas que adicionei ao código.
