Hello,
Perhaps this would be a faster way of typing this (yet still easy to read):

$(function(){
    $("fieldset").find("intput,select,textarea")
    .focus(function(){ $(this).parent().addClass("on"); })
    .blur(function(){ $(this).parent().removeClass("on"); });
});

Also note that http://www.jquery.com/api/ is an excellent resource for 
learning jQuery.

My suggestion:

$(function(){
    var toggle = function() { $(this).parent().toggleClass('on') };
    $('fieldset").find('input, select, 
textarea').focus(toggle).blur(toggle);
});

I'd choose this approach in order to avoid typing the class name "on" in 
more than one place (which may lead to errors if you want to change that 
one and forget it somewhere - not here maybe but in larger chunks of code).
