Which ACT Templates to modify for basket/checkout?

[GAViN™©]

I've just got my PC setup with Apache to act as a local server so can view my site. However when i goto view basket or the checkout page, the pages are still set to the original template design i chose, and therefore need modifying to work with my new look.

Which ACT_Templates do i need to modify for both the view basket screen and the checkout screen?

Thanks!

Act_PrimaryCheckout.html .. or keep maintenance to a minimum by using the Act_Primary.html under Design | Options | Layouts for the cart area
