Personally I don't like to show them until the customer gets into the secure part of the site, but that is just me. I usually put it up in the header on checkout, so it is very clear to them that there is a certificate in place. How you add it depends on the instructions you received from the certificate company. Some are just a simple image you add just like any other image, some have JavaScript verification. I'm guessing the GoDaddy ones are just an image because they are so inexpensive, so just add it like any other image.
