Noobie question linking to google CDN Jquery

I have just found out that it’s best to link to Google CDN as per this article

http://encosia.com/3-reasons-why-you-should-let-google-host-jquery-for-you/

However I am trying to use an image sliding script as seen on this template
http://www.websitetemplatesonline.com/free-template/redstorm.html

This calls in 3 scripts which are

<script type="text/javascript" src="lib/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="lib/jquery.tools.js"></script>
<script type="text/javascript" src="lib/jquery.custom.js"></script>

Now I see I can replace the 1st line with

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>

But what I am trying to work out is can the next 2 lines also be called from elsewhere this is my question that I cant find an exact answer.

Many thanks

Ian

For jQuery tools …

<script src="http://cdn.jquerytools.org/1.2.7/full/jquery.tools.min.js"></script>

For jQuery custom, you might not have a cdn for. But try looking for it at http://cdnjs.com/

The “custom” JS file is likely jQueryUI. When you customize that package on jQuery’s site and download it, the filename usually includes “custom”.

Also, here’s everything that google’s CDN hosts: https://developers.google.com/speed/libraries/devguide
