PHP Code for Registration Page

I want to add some goodies to my site's registration page.
#1- HTML link to Gravatar.com,
#2- Embed a video via HTML:
<object width="400" height="224" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0"><param name="src" value="http://s0.videopress.com/player.swf?v=1.03" /><param name="wmode" value="direct" /><param name="seamlesstabbing" value="true" /><param name="allowfullscreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="overstretch" value="true" /><param name="flashvars" value="guid=HNyK67JS&isDynamicSeeking=true" /><embed width="400" height="224" type="application/x-shockwave-flash" src="http://s0.videopress.com/player.swf?v=1.03" wmode="direct" seamlesstabbing="true" allowfullscreen="true" allowscriptaccess="always" overstretch="true" flashvars="guid=HNyK67JS&isDynamicSeeking=true" /></object>
#3- Text saying: "Want a profile pic you can use almost anywhere on the web, including here? You want a Gravatar."

Here's some of the registration code where this needs to be submitted:

<?php do_action( 'bp_before_registration_submit_buttons' ); ?>

<div class="submit">
<input type="submit" name="signup_submit" id="signup_submit" value="<?php _e( 'Complete Sign Up', 'buddypress' ); ?>" />
</div>

<?php do_action( 'bp_after_registration_submit_buttons' ); ?>

<?php wp_nonce_field( 'bp_new_signup' ); ?>

<?php endif; // request-details signup step ?>

Ok- what PHP should code should I use to insert the text, link and/or video?
