MySQL Performance: MySQL => optimize help for order by

I have the following query that uses a filesort.. Its a bit condensed since I'm not putting in other fields I am grabbing.

It is a bit slow.. for people with a lot of friends.. it could take around 2-3 seconds.

SELECT title,entryid FROM members INNER JOIN friends ON members.id=userid1 INNER JOIN entries ON members.id=userid WHERE status=1 AND userid2=2 

UNION 

SELECT title,entryid FROM members INNER JOIN friends ON members.id=userid2 INNER JOIN entries ON members.id=userid WHERE status=1 AND userid1=2 ORDER BY entryid DESC LIMIT 30;

Here is the explain

mysql> explain SELECT title,entryid FROM members INNER JOIN friends ON members.id=userid1 INNER JOIN entries ON members.id=userid WHERE status=1 AND userid2=2  UNION  SELECT title,entryid FROM members INNER JOIN friends ON members.id=userid2 INNER JOIN entries ON members.id=userid WHERE status=1 AND userid1=2 ORDER BY entryid DESC LIMIT 30;

|  2 | UNION        | friends    | ref    | userid1,userid2 | userid1 | 3       | const                     |  354 | Using where    | 
|  2 | UNION        | members    | eq_ref | PRIMARY         | PRIMARY | 3       | photoblog.friends.userid2 |    2 | Using index    | 
|  2 | UNION        | entries    | ref    | userid          | userid  | 4       | photoblog.members.id      |   11 | Using where    | 
|    | UNION RESULT | <union1,2> | ALL    | NULL            | NULL    | NULL    | NULL                      | NULL | Using filesort |

Now my friends table looks a bit like this

friends
-------------

userid1 | userid2
1         2
3         1
4         1


entries
----------------
entryID | userid | title
1          1       title1
2          2       title2
3          2       title3
4          4       title4
5          3       title5
