Your order will not ship or completed until payment is received.

The correct English would be:
Your order will not be shipped or completed until payment is received.

How can i edit this? I want to say:
Your order will not be completed until payment is received.

The file i am looking for is called:
checkout/guest_step_3  or guest_step_3 most likely the file would be .tpl
