In the checkout page, is there a way to have "or use" google checkout instead of it just staying right below the checkout button, its confusing for my customers

You can use CSS to remove the built-in checkout button. That way, the only one that appears is the Google Checkout button.

What we are looking for is to use both. So is there a way in CSS to have the "or use" between the buttons? or any other way, other than adding the "or use" to the graphic.

The easiest way would probably be to add 'or use' to the button. You could use JavaScript to dynamically add that text between then buttons as the page is rendered, but it'll likely not look right.
