I haven't heard much discussion of NTSC v PAL of late. Seems underwater videographers like at least 60p to gather enough detailed information and slow down fast moving action without degrading images. And I don't think I'd venture to 120p unless you really want to work with slow motion and don't mind that heinous crop.
Sony's autofocus is so good, there may not be much benefit in switching from the monitor to the viewfinder, which I would use if I was focusing manually. Plus, the viewfinder at 2.36 mil resolution isn't the greatest. I would keep the standard video on button and assign switching to a favorite menu item.
As primarily a stills shooter I tend to set white balance to AWB or daylight 5600k, but for video I will venture into setting manual white balance at depth, or AWB with a warming filter to 15m, and lights deeper than that.
I really like stabilization -- good stuff. Here is an unstabilized, unedited clip: A6000 in housing with 16-50 kit lens. AWB. This is Point Panic, a favorite south Oahu winter dive spot, with Diamond Head in the background. The camera was balanced on my knee.
