php-4.0.4pl1-9 then?  I think that should work OK, though I've never tried 
PHP 4 with shm personally.  (I don't think shm is your problem.)

Using the tarballs?  I presume you configured PHPLIB for shared memory
then since:

Good.

Yes; the session ID will stay with you until you log out or close and
reopen the browser.  The "2_" prefix is normal for shm.

Hm... there's nothing above that line?  Often "Cannot add header
information" is just a symptom of a previous error higher up.  Oh, one
known gotcha:  Double-check your phplib/session.inc file... make sure
there's no space after the final "?>" on the last line of the file.

See templates/ under horde/ and imp/; it's pretty easy to customize.
