To reposition the FB login button, you can place the code inside a div and control the div to position the box.
ie., put the fb embed code inside a div like this,
<div class="fb-login">
<fb:login-button show-faces="true" width="200" max-rows="1"></fb:login-button>
</div>
Now you can apply style to 'fb-login' class to position the fb button.
