CCK - How do I turn off fields on content creation?

I would like to set default values for fields and then make it so that during content creation they are not turned on.

More specifically, I want to create a node-product.tpl.php file that sets print $node->content['model']["#value"]; . Then, I want to disable product attributes.

I might be doing this wrong. What I am basically looking for is a create content forum that allows an admin to upload a picture and give it a title. That's all the admin will see when creating content. Then, when the admin goes to see the page he's just created, the site will have automatically filled in the item's SKU based on the title.
