JQuery :: Animated Menu - Show / Hide DIV

I am working on my portfolio site and I've come to a bit of a wall. I have a main navigation which, when clicked animates a div containing my content to be visible. I have this working fine but now I want to have external content loaded into this containing div when different navigation items are clicked, which I also have working, but I cannot get these to work together. First off, if the div is not shown I want the appropriate content to be loaded then the div to animate, and if the div is showing, I want it to hide, swap the content then animate. I am sure its just a case of structuring my code properly but I just cant seem to get it right.

Show the div
$(document).ready //content animate show (
function() {
$('.navigation a').click (
function() {
$('.content').stop().animate ({
marginTop : "0px" },{
easing : "easeOutQuint",
duration : 2000
})});})

Hide the div
$(document).ready //content animate hide (
function() {
$('#hide').click (
function() {
$('.content').stop().animate({
marginTop : "200px" },{
easing : "easeInQuint",
duration : 1500
})});})

And finally swap the content:
$(document).ready(function() {
// Check for hash value in URL
var hash = window.location.hash.substr(1);
var href = $('.navigation a').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-4)){
var toLoad = hash+'.php .content';
$('.content').load(toLoad)
}});

$('.navigation a').click(function() {
var toLoad = $(this).attr('href')+' .content';
$('.content').fadeOut('fast',loadContent);
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-4);
function loadContent() {
$('.content').load(toLoad,'',showNewContent())
} function showNewContent() {
$('.content').fadeIn('fast');
} return false;
});
});
