I've never used Cisco, so I can't comment on it's setup, but this looks almost right.
I'd try putting this in your conn.
    ike=3des-sha1-modp1024
    esp=3des-sha1
Also auto=add, means the connection will not start until the cisco requests it, if you
want openswan to start the conn right away you need to use auto=start.
Also, your using a version that's a bit old, 2.2, I'd recommend getting a recent version.

If your still not connecting, then send us your full log for that connection, which should be
less than a dozen or so lines, starting with something similar to this:
Nov 22 09:40:33 sheridan pluto[7376]: "stmarys-office-net-to-london-office-net" #1: initiating Main Mode
or
Nov 22 10:19:09 delenn pluto[26859]: "stmarys-office-server-to-london-office-server" #78: responding to Main Mode
