Are you planning to allow mobile devices in your company and realize you need a secure way of publishing the resources that the clients will access?

Well then I suggest you take a look at the Microsoft Forefront Mobile Configuration Starter book written by Fabrizio Volpe. In this book Fabrizio gives you an easy to follow guideline to get you started with using UAG as your mobile access solution. He also gives you many pointers to resources where you can dig deeper into the mystery of allowing mobile devices access to your internal resources.

I also recommend you take a look at my earlier post on how to use KCD to secure your infrastructure where i discuss how KCD can be used to secure mobile device access.
