I have read the Google page event documentation, but I am not sure I understand it correctly. I am new to Google analytics, and I have two questions:

1. Once I have google analytics enabled for my site (i.e. I have inserted the tracking code in my pages etc), do I need to set anything else up (at the Google end - i.e. in my Google analytics account)

2. It is not clear to me how the event data particularly, relating to how the data can be aggregated and analyzed.

For instance, if I want to track an event under category category for click action action, I will use the following code snippet:

<a href="some-uri.htm" onclick="_gaq.push(['_trackEvent', 'category', 'action', 'label']);">Do Something</a>

For the sake of simplicity, lets say I am interested in monitoring click events in my header and footer, and I want to find which pages the header and or footer is clicked most often.

How would I set things up so that I can analyze the header/footer clicks aggregated at the page level?
