How Can I Apply for Deferred Action?
At the moment, they haven't announced a process on how to apply for deferred action, but the process is expected to be announced 60 days after the June 15th announcement of the new policy (so in August 2012). You can't apply yet, unless you're already in removal or deportation proceedings. Although you can't apply yet, you can (and should) start collecting documentation showing that you meet the requirements. However, you shouldn't submit anything to the government yet, and you should talk to an immigration attorney before you do anything.
