I have seen a link to a script to take people to a different address if the screen size indicates a mobile device.

Are there are specific tools or advice for building a mobile device?
Is there a way to "emulate" a mobile browser for testing?
Which is the best CoffeeCup applicaiton to use for such developments?

thanks in advance for any advice

You don't need to 'emulate' a browser for testing any more. Using CC's RLM ( Responsive Layout Maker ) you can build a framework that is completely fluid ( automatically adjusts to ANY size viewing screen from desktop to mobile ). Check out RLM here: http://www.coffeecup.com/responsive-layout-maker-pro/

If you want a quick look at how your website will look at different sizes, try this: http://quirktools.com/screenfly/

I would definitely give RLMP a try and see how that works for you.

To answer your first question you can try this site as it will allow you to render the site to see it mobile:
