Issue with Customizing Calendar

Question 1: I copied these lines from instructions (found here: http://www.noeltock.com/web-design/wordpress/events-custom-post-types-fullcalendar-json-wordpress/) for integrating a custom ajax feed into the calendar and added these lines to the functions.php:

// - fullcalendar -
wp_enqueue_script('fullcalendar', (get_bloginfo('template_url')) . '/js/fullcalendar.js', array('jquery'));
wp_enqueue_script('gcal', (get_bloginfo('template_url')) . '/js/gcal.js', array('jquery'));

The problem is the script is not loading correctly and I get the following errors:
http://www.telitrax.com/wp-content/themes/bivio/js/fullcalendar.js?ver=4.1 Failed to load resource: the server responded with a status of 404 (Not Found)
http://www.telitrax.com/wp-content/themes/bivio/js/gcal.js?ver=4.1 Failed to load resource: the server responded with a status of 404 (Not Found)
2http://www.telitrax.com/wp-content/themes/bivio/css/fullcalendar.css Failed to load resource: the server responded with a status of 404 (Not Found)

Question 2: In functions.php I have this line:

$jsonevents = 'https://demo.survos.com/member/device_calendar_tacman?start=2014-09-28&end=2014-11-09&_=1417691096993';

I need the logged in user’s subject ID instead of “tacman”. The subject ID defined in profile builder plugin.
