If you're working with PHP and need a single array of comments to loop through this function might come in handy:

public function getComments($objectID){
    $user = $comment =array();
    $q1 = "/fql?q=".urlencode("SELECT  id, fromid, text, time , likes FROM comment WHERE object_id ='$objectID' ");
    $res = $this->api($q1);
    $com = $res['data'];

    $q2 = "/fql?q=".urlencode("SELECT uid, name, username, pic_small, current_location FROM user WHERE uid IN (SELECT fromid FROM comment WHERE object_id ='$objectID' )");
    $res = $this->api($q2);
    $usr = $res['data']; 

    foreach($usr as $k=>$v){
        $user[$v['uid']] = $v;
    }
    foreach($com as $cmnt){
        $comment[$cmnt['id']] = $cmnt;
        $comment[$cmnt['id']]['user'] = $user[$cmnt['fromid']];
    }
     return $comment;
}

Returns a single array of comments with the commentID as key:

Array(

You could match these results up by looping over the comments and matching the fromid to an id from the users response.

For example:

    var comments = response[0].fql_result_set;
    var users = response[1].fql_result_set;    

    //loop through the comments
    for(var i = 0, j = comments.length; i<j; i++){

        for(var x = 0, y = users.length; x<y; x++){
             if(comments[i].fromid == users[x].id){
                 //we have a match, this comment is from user users[x]
                 //process users[x]
                 //break the inner for loop, since we already have a match
             }
        }

    }
