I had the same plan as you did, farmgirl, before my DD was born, and for exactly the same reasons (although I never read Gina Ford...).

But I found that DP would get home and take care of the whole evening, bath, cuddle, bed routine and give me a break then. I also found that my DD was such a great bfer and got so very efficient at it that I was hardly up at all during the night and was back asleep within 45 mins of getting up. She always fell asleep at the breast and I never had the pacing the floor kind of unsettled behaviour I was expecting. So in the end, because I actually got plenty of sleep, we didn't bother to go with the expressing for a bf thing. I did express when DD dropped a feed or I needed to relieve engorgement, so I had bottles to give to anyone babysitting her.

I think you'd be best off waiting to see how you go and then deciding whether it will work for you or not.
