I don't think they are needed with ABR either. Setting ratetol higher than default may be a good idea in your case, but I wouldn't touch those other settings.

Also, you seem to be tweaking lots of things back and forth between the presets and the resolution-specific options. Personally I'd just copy x264's medium or slow preset and only change things that are required by the playback devices.

Do you think there would be likely drops in quality with the use of VBV?
That depends on many things. If you can set it high enough (perhaps 15 Mbps with a 10 second buffer for 1080p), it would probably be fine considering your OTA sources.
