[texhax] how to last-name-first for all authors with biblatex

[Christopher W. Ryan]

I'm trying to convert myself from bibtex to biblatex, and I'm having 
trouble figuring out how to get bibliography entries to look like:

1.  Author AB, Otherauthor CD, and Lastauthor FG.  ......

I'm on Ubuntu 10.04, which has unfortunately a rather old version of 
Biblatex: 0.81.

Here's what I've tried so far, in my preamble:

\usepackage[margin=1in]{geometry}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage[style=numeric-comp, sorting=none, firstinits=true, 
terseinits=true, minnames=3, maxnames=6]{biblatex}
\DeclareNameAlias{labelname}{last-first}
\bibliography{HeatWaveReferences}

I use \supercite{} as my cite command.

This produces:

1.  AB Author, CD Otherauthor, and FG Lastauthor  .....

I'd be grateful for any advice.

Thanks.
