Until the first one is put in, you will see zero comments, and thus (if you put the link in the _comment (singular) partial, there won't be any link, because the _comment partial will be rendered zero times.

Unless you are planning to allow comments on comments (some sort of threaded nesting structure), then this will look awful and make no sense. So if you are somehow able to render the first comment, the second one will get its own Add Comment link. Beyond that, in order to inject the form into the page the way you want to, you need to insert the form into some identifiable DOM object, which you didn't provide in your sample templates.
