Have you tried any of the browser developer tools to make sure 
jquery-ui.???.js is getting loaded. If you're using FireFox then FireBug 
is good for that. If you're using a WebKit based browser (Safari or 
Chrome) then they have the built-in Web Inspector. With any of those 
tools select the "Resources" tab and look for the JavaScript files 
downloaded by the browser. That will tell you if jQuery UI is getting 
loaded correctly. If it is getting downloaded these tools also have 
JavaScript debuggers built into them, which allow you to set breakpoints 
and step through execution of JavaScript.

It would serve you well to learn how to use these tools.

They same way you install any JavaScript files in Rails. Put them in the 
proper place and make sure your layout (or whatever renders the <head> 
tags) loads the required JavaScript files.
