Your no-electric list looks pretty good to me...(well, it wouldn't be 'good', but you know what I mean!)
I agree that flap deployment would be normal, but you'd have to 'feel' the changes with each setting since the flap position indicator would be u/s (L AC transfer bus).
I've also got down here that the standby attitude indicator and standby altimeter are powered by the standby DC bus, so again with no gennys and no battery you'd need an HMG for that...Looks like you'd have a standby ASI though, so let's hope for good VMC and daylight eh?
