Try changing your JS to this:
<script type="text/javascript">
$(function () {
$("#tags").autocomplete({
source: usernames
});
});
</script>
If I'm guessing at your .Net code correctly, you're registering "usernames" as the javascript array, but trying to use the empty 'availableTags' as your autocomplete source.
Note: this may be completely off-base here - I haven't actually used ClientScript.RegisterArrayDeclaration or the jQuery autocomplete plugin in code I've written before.
