Hi,
I will try and help. It helps to "see" what the settings do, so I recommend downloading the PC control software from KO:

Download both the "VFS-1 Manager" and "Servo Program" tools and load them up. You don't need the program lead to run them and see what the settings do. Best of all you see graphical info and not just a series of numbers
ALL SELECTIONS does as you say, moves all throttle points up or down in single steps. The number on screen at that point is the average throttle value. Again, you are correct and should really only do this one step at a time.
As for the servo, I am not sure as I have never tried to reprogram mine, but have a look at the software and I am sure it will become clear
