Need help combining multiple javascript files

ASP.NET

I just read an article by Omar Al Zabir "HTTP Handler to Combine Multiple Files, Cache and Deliver Compressed Output for Faster Page Load". I am trying to make my asp.net web application faster.
I have only one reference to an external .js file, but YSlow reported as many as 15! And I did find them in the page source:

As I understand, they are from ajax stuff. Now as I want to combine them into one, I need to specify them in a set inside of my web.config. Moreover, I need to change <link> and <script> tags throughout your website to point to HttpCombiner.ashx, but how can I do that, if it is not in my .aspx code?
Could you please help?
Thanks.
