 if (is_array($GLOBALS['TSFE']->fe_user->user)) {
    // user is logged in

 fe_user is a tslib_feUserAuth object (see corresponding class)

 first of all you can always use
    get_class_methods($object) and
    get_class_vars($object) on objects
 and use the debug function to output any object/array data...
 debug($GLOBALS['TSFE']);
 secondly install the extension "extdeveval" and you'll get a row with
 "dev links" in the top frame in the backend 
 (= links to the API documentation)
