Hi
I had similar problem as you and i agree that asual.com don't help much. Terrible guide/documentation.
I solved my problem with jquery-easytabs-plugin from http://www.alfajango.com/blog/jquery-easytabs-plugin/
I use it with tabs but i guess it posble to use with other things as well. Very nice plugin and it work very good. It use jquery-hashchange-plugin as standard and as they recommend but if you want you can use jQuery Address plugin with it instead. Just Include either the jQuery HashChange plugin or that jQuery Address plugin from asual.com with jquery-easytabs-plugin.
I hope this help, it helped me much (thanks to the author Steve Schwartz ) and i can rely recommend it. The guide/documentation is very good.
Here is version 2.2, i think that is the latest one.
