SFO - LHR 4 Oct 2009 OOPS!

I may have royally messed up.
In an effort to make our Anniversay that much better, i moved up my family's flight to London two days. It was the middle of the night and i wantedto make it a surprise and I thought iwas doing a good thing. Now I'm not so sure.
My main issue has to do with seat assignments. My wife and I are travelling with our 7-year old son in PE. When I made the outgoing flight switch, the VA Red Level Flying Club lady never mentioned seat assignments.
When it dawned on me that I didn't have seat assignments, I called back. I was told that I had to wait until 24-hours before the flight.
I had us booked in A/C/D seat configuration, my wife and son in A and C with me accross the aisle in D. Now I'm stuck figuring out how to work this out at hte last minute.
Further, I was informed today that I cannot request help over the phone - seat assignments have to be done via the internet only and calling Flying Club won't help. I'm sot sure whet my internet evailablity will be at 1630 on Oct 3rd.
SO - any advice for a well intentioned, but poorly foresighted husband and father like me..? All suggestions/advice is sincerely appreciated.
