Yes, this module supports all three tracking options. Each is configurable from within the admin (except ecommerce tracking which is automatically put into place upon install.)
You will need to turn on the options from within your Google Analytics account as well (make sure your site is set to an "ecommerce site" in your profile edit area.)
It also automatically adds the required code to the checkout success page as well. This can only be viewed if you complete a successful checkout of course and then "viewing source" on the thank you page.
There should be no need to confirm that though providing you selected that option (adwords tracking) from within the admin, entered your adwords tracking id (different from teh analytics one) and are running a Google Adwords campaign.
Hope that helps.
