Adding Affiliate visitor tracking JavaScript

[battles]

I'm trying out an affiliate program and it needs some custom JS added to the home page and to the thank you page:

Tracking Visitors
To track visitors, copy and paste the following code just above </body> on your website.

Tracking Purchases
Tracking purchases can be accomplished by adding the following javascript on your Thank You page.

I'm relatively sure that I will add the Purchade script to:  /templates/orderforms/cart/complete.tpl

Where would the visitor tracking go?

Also it needs to be wrapped in - {literal} {/literal} , correct?

Is there a custom js file I should add and call so it doesn't get overwritten by updates?

if you want to avoid changes getting overwritten due to updating, then you'd be better off using hooks rather than editing the templates.

that's usually a ClientAreaFooterOutput hook.

that's a ShoppingCartCheckoutCompletePage hook.

there should be plenty of examples hooks previously posted to cover both parts - they can be put in the same .php file.
