I am not clear on how to create the bold text unnumbered sections and I don't want to have more then 3 Levels

Answer 1

For unnumbered sections you can use \subsection*{subsection name}. The levels of table of content you can define with \setcounter{tocdepth}{2} or numbering with \setcounter{secnumdepth}{2}.

Unnumbered section:

\chapter{First One}
\section{A section}
\section{B section}

\section*{unnumbered section}

Update:You can add them to table of content manualy with \addcontentsline{toc}{section}{section name}.

Only 3 Levels in toc with \setcounter{tocdepth}{2}.

\chapter{Second chapter}
\section{A section}
\section{B section}
\subsection{subsection}
\subsubsection{subsection}

Full Code example:

\documentclass{scrreprt}
\usepackage{hyperref}% http://ctan.org/pkg/hyperref
\setcounter{secnumdepth}{2}   
\setcounter{tocdepth}{2} 
\begin{document}
\tableofcontents

\chapter{First One}
\section{A section}
\section{B section}

\section*{unnumbered section}
\addcontentsline{toc}{section}{unnumbered section}

\section{fcf}
\chapter{Second chapter}
