...I am using VirtueMart 1.1.2 and the google checkout button does not appear. Any help would be massively appreciated. Many thanks.

Is googlecheckout your only payment method?

Make sure you follow this step in the readme.txt that comes with the module

MODIFICATIONS For VirtueMart 1.1.x. (file edits)

The files in this folder:
/components/com_virtuemart/themes/default/templates/*
Have already been modified for 1.1.0. Just copy those files and
remove the extension .vm1.1.x off the end of the file name....

Is there a quick way I can add the google checkout button underneath the "Google Checkout" option in the list billing options page? And have that essentially advance in the cart to the confirmation page for google checkout cutomers?

note really because the other payment methods in the list you have to select the radio button next to it to select it. If you show the button it people will click on it instead of selecting the radio button and then the rest of the virtuemart checkout will be skipped.
