Answer 1

I'm not sure what all the get and makeArray stuff is for but I think you're looking for index :

Search for a given element from among the matched elements.

So given some anchors:

<a>Zero</a>
<a>One</a>
<a>Two</a>
<a>Three</a>
<a>Four</a>

you could do things like this:

$('a').click(function() {
    var i = $('a').index(this);
    // i is the index of the clicked anchor within all the anchors.
});

How about this:

$('a').click(function(){
console.log($(this).index());
})
