You're welcome.

1) You can theme the Cart Contents pane on the checkout screen and add anything you want there. For example, I add shipping and discounts and an order subtotal, right below the cart contents. This seems more intuitive to me - putting all of the cost information in one place.

2) I think this must be due to your theme. Mine is left justified. You should have all the CSS id's and classes you need to re-arrange it as you like. (You can override them in your style.css rather than editing the module CSS directly too...not sure if that's what you meant)

Best,
