How to disable a widget when dependent plugin is inactive?
well first of all, is_plugin_active takes the name of the plugin sub-directory/file, so passing it a classname won’t work.

the_post_thumbnail call removing li in code
the_post_thumbnail(); function is not supposed to be echo-ed! get_the_post_thumbnail(); is meant for that. Refer to the linked WordPress Codex pages. Try this instead: <?php // Wraps post-thumbnail in li tags echo ‘ <li>’ . get_the_post_thumbnail(‘talent-featured-thumb’) . ‘</li>’; ?>

Validating widget’s configuration data on Admin page
@tf is almost there, I think. You can use JS on your widget’s admin form, as I’ve done it before (though not for validation). Within your widget’s constructor, add an action: add_action( “admin_print_scripts-widgets.php”, array( __CLASS__, ‘register_my_validation_script’ ) ); Then create the corresponding function inside your widget’s class: function register_my_validation_script() { wp_enqueue_script( ‘my-script-handle’, plugins_url( ‘/my-validation-script.js’, __FILE__ … Read more
disbale default widgets on theme activation
Default widgets are not usually activated with the theme. Themes add default widgets in the sidebar template file.
