imprim, save and product details button

[mjandia]

Hello,

I would to like to change different buttons on VM2 with joomla 1.5 :

-  the "save" button when i check the shipment and payment method, I want to put "confirm";

- the "détails product" button has a grey color and "ask a question on this product" too  how to change the color of the button or the color of the text ;

- the imprim button on IE9  in the account management doesn't appears correctly.

Thanks for your help
