Answer 1

If you want to make your hand-edited bibliographic items compatible with the format that natbib expects, you have to change

\bibitem[\protect\citeauthoryear{Wang and Vergara-Niedermayr}{2008}]{wang08com} ...

to

\bibitem[Wang and Vergara-Niedermayr(2008)]{wang08com} ...

(Aside: Who taught you to write \protect\citeauthoryear{Wang and Vergara-Niedermayr}{2008}]?!)

Mainly, you should make an effort to learn how to use BibTeX and/or biblatex.

A full MWE (note that your code snippets are compilable):

\documentclass{article} % "singlecol-new" ?
\usepackage[authoryear]{natbib}
\usepackage{stfloats,mathrsfs}

\begin{document}
\citet{wang08com}

\begin{thebibliography}{9}

\bibitem[Wang and Vergara-Niedermayr(2008)]{wang08com}
Wang, F. and Vergara-Niedermayr, C. (2008) `Collaboratively Sharing
Scientific Data', {\itshape CollaborateCom}, pp.\ 805--823.

\end{thebibliography}
