[jQuery] new at jquery; can't get settimout or callback to work


hi guys. help would be very much appreciated.
i downloaded a slideshow script called galleria. problem is when it
loads, my header image, which i have sliding in, gets really choppy.
so, i want the galleria script to execute after the header animation
is done.
i haven't been able to get anything to work, including attempting
callback, hacks, and settimeout. here's my current code, which does
not delay the beginning of the galleria script. what am i doing
wrong, very curious?
also, if this can be done more efficiently, please do tell.
<script type="text/javascript">
$(document).ready(function(){
$('#headerimg').show("slide", {direction: "left"}, 3000)
});
</script>
<script type="text/javascript">
$(document).ready(
setTimeout(function () {
$('ul.gallery').galleria(
{
            history : false, // activates the history object for bookmarking,
back-button etc.
            clickNext : true, // helper for making the image clickable
            insert : '#main_image', // the containing selector for our main
image
            onImage : function(image, thumb) { // let's add some image
effects for demonstration purposes
                    //image.css('display','none').fadeIn(3000);
                //caption.css('display','none').fadeIn(3000);
                // fetch the thumbnail container
                var _li = thumb.parents('li');
                // fade out inactive thumbnail
                _li.siblings().children('img.selected').fadeTo(500,0.3);
                // fade in active thumbnail
                thumb.fadeTo('fast',1).addClass('selected');
                // add a title for the clickable image
                image.attr('title','Next image >>');
            },
            onThumb : function(thumb) { // thumbnail effects goes here
                // fetch the thumbnail container
                var _li = thumb.parents('li');
                // if thumbnail is active, fade all the way.
                var _fadeTo = _li.is('.active') ? '1' : '0.3';
                // fade in the thumbnail when finnished loading
                //thumb.css({display:'none',opacity:_fadeTo}).fadeIn(300);
                // hover effects
                thumb.hover(
                    function() { thumb.fadeTo('fast',1); },
                    function() { _li.not('.active').children('img').fadeTo('fast',
0.3); } // don't fade out if the parent is active
                )
            }
        })
    }, 4000
    );
    );
    </script>
