jQuery .animate/.each chaining

I'm trying to combine matching something like:

$(".item").each(function(i) {
    //animation here
});

with jQuery's inherent chaining functionality that forces the animation to wait until the previous animation has completed, e.g.:

$(".item").each(function(i) {
    $(this).animate({marginLeft:"0"}, 60);
});

And then trigger a .load function after the animations have completed. Basically, I want to fade four items out in order [one after the next, not all at once], then load four new items into the same div, replacing the first four.

How can I do this in a reusable/variable way?

$("#more:not(.disabled)").live("click", function(event) {
    event.preventDefault();

    var urlPieces = (event.target.href).split("/");
    var nextURL = urlPieces[urlPieces.length - 2] + "/" + urlPieces[urlPieces.length - 1];
    var items = $(".item");
    var itemCount = items.length;   

    items.each(function(i) {
        var passthru = this;
        window.setTimeout(function() {
            $(passthru).animate({opacity:"0"}, 60, function() {
                if (i == itemCount - 1) {
                    $("#browse").load(nextURL + " .item, #controls", fadeInNew);
                }
            });
        }, 60*i);
    });
});

fadeInNew handles the new one by one fade in elsewhere, but this was what I was looking for more or less with a bit of extra code around it to maybe shed some light on what was happening (there's a next arrow with a url in its href, if javascript is on, I need the URL of the next page relative to the current, if it's off, it follows that url as an href and loads a new page which has the same content on the page except for the new items that would have been $.load-ed.
