The alltt package provides a beefed up verbatim environment where \ and {} are not treated literally. A literal backslash can be inserted with \textbackslash, however, it does not have the same teletype font as the rest of the verbatim text. I tried some variataions such as \texttt{\textbackslash} but these don't seem to help. Any ideas how to insert a backslash (or curly braces) in teletype font when using alltt?

With listings you just need to add breaklines=true to enable line breaking, you can also include commands that are to be executed by defining an escapechar which lets you put custom formatting commands.
If you don't want the italics formatting applied to the keywords, just remove the setting keywordstyle={}.
\documentclass[border=2pt]{standalone}
\usepackage{xcolor}
\usepackage{listings}
\newcommand{\somewhatImportantCode}[1]{\textcolor[rgb]{0.0,0.35,0.6}{#1}}
\newcommand{\veryImportantCode}[1]{\textcolor[rgb]{0.0,0.5,0.9}{#1}}
\lstset{
language=C,
basicstyle=\ttfamily,
showstringspaces=false,
breaklines=true,
keywordstyle={\textit},
%morekeywords={text},% list your attributes here,
escapechar=\&% char to escape out of listings and back to LaTeX
}
\begin{document}
\begin{lstlisting}
&\somewhatImportantCode{\#include <iostream>}&
int main()
{
&\veryImportantCode{std::cout <<}& "Hello World!" &\veryImportantCode{<< std::endl}&;
return 0;
}
\end{lstlisting}
\end{document}
Package alltt defines an environemnt alltt that uses a list environment internally. Therefore it cannot be used the same way as \verb or \texttt.
The main point of package alltt is the unchanged use of \, { and }. The following macro \textalltt sets verbatim catcodes for its argument except for the three characters.
\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\makeatletter
\newcommand*{\textalltt}{}
\DeclareRobustCommand*{\textalltt}{%
\begingroup
\let\do\@makeother
\dospecials
\catcode`\\=\z@
\catcode`\{=\@ne
\catcode`\}=\tw@
\verbatim@font\@noligs
\@vobeyspaces
\frenchspacing
\@textalltt
}
\newcommand*{\@textalltt}[1]{%
#1%
\endgroup
}
\makeatother
\begin{document}
Verbatim text: \textalltt{Hello \textbf{\textsl{world}}}.
\end{document}

This has nothing to do with alltt. You need T1-encoding. Without it \textbackslash is taken from the symbol font. Check the difference:
