Navigation Hover / Slideshow / Display Inline Content Override Each Other

I am using javascripts in my index page. For navigation hovering, slideshow and the other one is for displaying inline content in a form of a lightbox. But the problem is they cant seem to work together. i have to remove the inline content JavaScript for the slideshow and navigation hovering JavaScript to work. All of them are in the header. I want to merge all these together so that they all work.

Navigation hover javascript:
<script type="text/javascript">
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
}function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
[Code] .....

Slideshow Javascript:
<script type="text/javascript">
$(document).ready(function() {
$('#slider').s3Slider({
timeOut: 3000
});});
</script>

Inline content Javascript:
<script type="text/javascript">
$(document).ready(function() {
$().piroBox_ext({
piro_speed : 700,
bg_alpha : 0.5,
piro_scroll : true // pirobox always positioned at the center of the page
});});
</script>
