EDIT: I've added the code to change (as requested in a comment) the format of the chapter headings.
To change the format of the chapter entries in the ToC ou can use the tocloft package; to change the format of the chapter headings, you can use the titlesec package. A little example:
\documentclass{scrbook}
\usepackage{titlesec}
\usepackage{tocloft}
\renewcommand\cftchapfont{\scshape }
\renewcommand\cftchappresnum{ Chapter\ }
\renewcommand\cftchapaftersnumb{\newline\normalfont}
\renewcommand\cftchapleader{\cftdotfill{1}}
\renewcommand\cftchappagefont{\normalfont}
\titleformat{\chapter}[display]
{\normalfont\Large\itshape\raggedleft}
{\chaptertitlename\ \thechapter}{10pt}
{\normalfont\Huge}
\titlespacing*{\chapter}
{0pt}{10pt}{20pt}
\begin{document}
\tableofcontents
\chapter{Test chapter}
\end{document}
