How to remove blocks/modules

Taking a stab at this . . . .

You should be able to remove the newsletter block code at app/deisign/frontend/default/f002/templates/page/html/footer.phtml

Code:

<div class="box mini-newsletter">
    <h4><?php echo $this->__('Newsletter Sign-up') ?></h4>
    <form action="<?php echo $this->getUrl('newsletter/subscriber/new') ?>" method="post" id="newsletter-validate-detail-footer">
    <fieldset>
        <legend><?php echo $this->__('Newsletter') ?></legend>
        <!--
                    <?php if( $message = $this->getErrorMessage() ): ?>
                        <p class="error"><?php echo $message ?></p>
                    <?php endif; ?>
                    <?php if( $message = $this->getSuccessMessage() ): ?>
                        <p class="success"><?php echo $message ?></p>
                    <?php endif; ?>
                    -->
        <button type="submit" class="form-button-alt f-right"><span><?php echo $this->__('Subscribe') ?></span></button>
        <input name="email" type="text" id="newsletter-f" class="required-entry validate-email input-text" />
    </fieldset>
    </form>
    <script type="text/javascript">
    //<![CDATA[
        var newsletterSubscriberFormDetail = new VarienForm('newsletter-validate-detail-footer');
    //]]>
    </script>
</div>

To disable the languages block . . . .

In the Admin panel:
-- Select: System--Manage Stores
-- Open up German store and select disable
-- Do the same for the other langauges

This is a way to hide the language switcher -- as you have not deleted anything and can be switched back on again
