V7/Oudie settings

I know there was a thread about this awhile ago, but I know there are at least a few people with a V7/Oudie/Nano setup. I just bought everything I need from Cumulus (great service BTW), and I'm stuck in my house fiddling with it until soaring season starts. I realize these things are very flexible and can be made very personal, but I want to get an idea of how the experienced pilots set it up. So, what settings do you use for:

V7:
--Bitrates (I chose 115200 with Nano and Oudie, any reason not to?)
--Upper/lower number in Thermal/SC modes?
--Auto SC (I chose GPS mode to auto-switch)?
--Vario needle filter?

Oudie:
--Which navboxes?
--How do you use the "Page 1/2" feature? I thought I'd make one page to work with the V7, then one page in case the V7 fails or my battery runs out, and the Oudie is running by itself on the internal battery. Thoughts?
--Internal GPS or GPS input from Nano?


Nano:
--It turns on with the master switch, any way to make it turn off with the master switch too?

Any other settings you find particularly useful on either device? Thanks for helping me combat the winter blues.
