I think it would be good to have the tracking in the popup_shipping_estimator.html page.... any ideas of how to do this?

Two things.
1) To add it to that page (since it does not use the standard tpl_main_page.php file) you would need to add it to that page along (manually).
2) I would NOT put the shipping estimate into a pop-up anyhow. It hurts conversion as mentioned in my 20 Ways book and at this link:
Shipping Estimate in a Pop-Up? Why it Hurts Your Conversion, and What You Can do to Fix it.
