As to your questions: The Shortcuts component is no more available, because it is deprecated. We will update our product documentation accordingly. For more details on how to create and use shortcuts in Q1 2011, please refer to the following help article
As to your second question - there is not a straight way of binding the menu to user privileges. However, you can customize the menu items and disable/remove them as you would like at run time according to your user account management.
Let me know if you have any additional questions.
