remove the border around "call for price" and reposition "ask us" button

hi all,
Recently i installed the "ask a question" add-on.

I enabled the "call for price" function and by deleting the text "call for price" in english.php, i.e. define('PRODUCTS_PRICE_IS_CALL_FOR_PRICE_TEXT',''). I now only have the button of "call for price" on the product listing page.
However, the page still looks a bit messy with a box around where the "call for price" text was.

Please tell me how to-
1. remove the white box
2. move the "ask us about this product" button to the left hand side, just under the product picture

Thanks all!
