There are several actions you could hook onto, most useful probably "init" or "widgets_init". Both are run before any output is printed, so you can redirect from those.

For a list of actions, see http://codex.wordpress.org/Plugin_API/Action_Reference

Example:

<?php add_action('widgets_init', 'my_redirect_function'); ?>
