Sorting of the bibliography requires that you have an external database of entries rather than a hand built list. In your case your external file mybib.bib could be:
@Article{art,
author = {Art, John},
title = {John's Article},
journal = {J. Jour.},
year = 2006,
volume = 7,
pages = {12-45}
}
@Book{fart,
author = {Fart, Peter},
title = {Travelling at speed},
publisher = {P. Press},
year = 2009,
address = {Sometown}
}
To use this in your document there are two approaches: (1) traditional bibtex; (2) modern biblatex.
Bibtex approach
Choose a style for the bibliography via \bibliographystyle. Choose the database file and print the bibliography via \bibliography{mybib}. As you seem to want your authors listed as Lastname, Firstname then one choice is the apa style, which requires the natbib package; pass the option numbers to this package to get numerical citations.
\documentclass{article}
\usepackage[numbers]{natbib}
\begin{document}

eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad
minim veniam, quis nostrud exercitation ullamco laboris nisi ut

reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla
pariatur. Excepteur sint occaecat cupidatat non proident, sunt in
culpa qui officia deserunt mollit anim id est laborum~\cite{art}.
\bibliographystyle{apa}
\bibliography{mybib}

Biblatex approach
Load the package biblatex, with style=numeric for numerical citations. To get Lastname, Firstname in the bibilography use the command \DeclareNameAlias{default}{last-first}. Point to your database via \addbibresource{mybib.bib}. Put \printbibliography at the place in you file you want the bibliography to appear.
\documentclass{article}
\usepackage[style=numeric]{biblatex}
\addbibresource{mybib.bib}
\DeclareNameAlias{default}{last-first}

I can think of only two things that may have happened to your document:
you are not using the genuine elsarticle-harv bibliography style; or
after changing the argument of \bibliographystyle to elsarticle-harv, you did not re-run LaTeX, BibTeX, and LaTeX twice more to fully propagate all changes stemming from the change in the argument of \bibliographystyle.
For sure, the genuine elsarticle-harv bibliographystyle (a) abbreviates the first and middle names of authors and places the initials after the surname and (b) sorts the entries alphabetically.
\RequirePackage{filecontents}
\begin{filecontents}{mybib.bib}
@misc{bloggs:2010,
author = "Joe Bloggs",
title = "Thoughts",
year = 2010,
}
@misc{author:2016,
author = "Annie Aardvark and Zebulon Zwicky",
title = "Deep Thoughts",
year = 2016,
}
\end{filecontents}
\documentclass[authoryear]{elsarticle}
\bibliographystyle{elsarticle-harv}
\begin{document}
\citet{bloggs:2010}, \citet{author:2016}
\section*{References}
\bibliography{mybib}
\end{document}
Best Answer
The bibliography style depends solely in the conference's template, as this varies from each one. It usually is
\bibliographystyle{IEEEtran}, but could also take the form of\bibliographystyle{IEEEbib}or any other like the ones you mentioned (such asIEEEtranS).You should really pay attention to your conference's specs, or if you are unsure then contact any of the organizers.
Regarding the keywords, I would keep my recommendation: stick to the template.
