Sam's answer is the best so far, but I think map would be a better choice than each in this case. You're transforming a list of elements into a list of their values, and that's exactly the sort of thing map is designed for.

var list = $("td.title_listing input:checked")
    .map(function() { return $(this).val(); })
    .get().join(', ');

Edit: Whoops, I missed that CMS beat me to the use of map, he just hid it under a slice suggestion that I skipped over.
