Citation style and arranging references

Question

Following is the latex code provided by @Mike Renfro from Putting Serial Numbers in References

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{refs.bib}
@BOOK
    {KandR,
     AUTHOR  = "Kernighan, Brian W. and Ritchie, Dennis M.",
     TITLE   = "{The C Programming Language Second Edition}",
     PUBLISHER = "Prentice-Hall, Inc.",
     YEAR = 1988
}
\end{filecontents*}
\usepackage[bibstyle=numeric,citestyle=authoryear,backend=bibtex]{biblatex}
\addbibresource{refs.bib}

\defbibenvironment{bibliography}
{\enumerate{}
{\setlength{\leftmargin}{\bibhang}%
\setlength{\itemindent}{-\leftmargin}%
\setlength{\itemsep}{\bibitemsep}%
\setlength{\parsep}{\bibparsep}}}
{\endenumerate}
{\item}

\renewcommand*{\nameyeardelim}{\addcomma\space}

\begin{document}

In 1988 C was totally awesome. \autocite{KandR}

\printbibliography 
\end{document}

However in the text at same time if I have to use (Kernighan and Ritchie, 1988) and at some places Kernighan and Ritchie (1988) then what will be the citing style for second scenario.

Moreover in references, i also need them to appear like this:

1. Kernighan, B.W. and Ritchie, D.M. The C Programming Lan- guage Second Edition. Prentice-Hall, Inc., 1988.

ie last name appearing first and accordingly all refernces are arranged in alphabetically order according to last name of first author.

How it can be done. Please help.

Answer 1

You need to specify the sorting option at loading time (you probably want nty: "name-title-year" and nyt: "name-year-title", for more sorting options look at pp. 44 sq. of the biblatex documentation and the sectioned linked from there).

The call to biblatex would then read (with "name-year-title" sorting)

\usepackage[bibstyle=numeric,citestyle=authoryear,backend=bibtex,sorting=nyt]{b‌​iblatex}

To change the name format, go with

\DeclareNameAlias{default}{last-first}

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@BOOK
    {KandR,
     AUTHOR  = "Kernighan, Brian W. and Ritchie, Dennis M.",
     TITLE   = "{The C Programming Language Second Edition}",
     PUBLISHER = "Prentice-Hall, Inc.",
     YEAR = 1988
}
\end{filecontents*}
\usepackage[bibstyle=numeric,citestyle=authoryear,backend=bibtex,sorting=nyt]{b‌​iblatex}
\addbibresource{\jobname.bib}

\defbibenvironment{bibliography}
{\enumerate{}
{\setlength{\leftmargin}{\bibhang}%
\setlength{\itemindent}{-\leftmargin}%
\setlength{\itemsep}{\bibitemsep}%
\setlength{\parsep}{\bibparsep}}}
{\endenumerate}
{\item}

\DeclareNameAlias{default}{last-first}
\renewcommand*{\nameyeardelim}{\addcomma\space}

\begin{document}

In 1988 C was totally awesome. \autocite{KandR}

\printbibliography 
\end{document}
