jQuery Common Coding tips:
1, less code by chain coding
2, Use data method instead of storing data inside the DOM.
    

 $('selector').data('meaningfullname', 'this is the data I am storing');

// then later getting the data with

$('selector').data('meaningfullname');

3, If you are Manipulating the DOM a lot, use livequery.(1.3)
 

    $('div.edit').livequery('click', function(){

//go into edit mode

});
