JQuery :: Getting Array Of Selected Options?

I have a product page that allows each specific item of clothing to have any number of various options. For example the admin may allow that a specific jersey can have your last name on the back and your team number, or maybe your nickname on the sleeve. These options each have an additional price, the name on the back may be $3.00, the number $2.00 and the nickname $5.00. I currently have a function like below that adds the additional fee to the total when you fill in that text box:

$('input').blur(function() {
var option = $(this).attr('id');
var value = $(this).val();

[code]....

and on the shopping cart I want to display:

Custom Name: Williams
Custom Number: 17
Custom Nick Name: Booger

I can use PHP to convert customName to Custom Name by looking up that option in the options db table but how do I build the JavaScript Array before I pass it to $_POST? Each element should have the value and price and it's key should be the options name...
