Just add <strong></strong> tags around the variable i.e.

if($post[field8]) $html .= '<dt>Wii</dt> <dd><strong>'.$post[field8].'</strong></dd>';

That should do that part. For your second question firstly I'd recommend looking at the Field Required option for the profile field (assuming you've used a profile field yea?) If you set that to yes always it forces them to set it before they can use the forums (existing/new members).
