I use DATA A. You want compression disabled (and equalization disabled,
coming soon!) and selecting DATA A does that. The ALC in DATA A is also
optimized for steady average level audio signals so it won't cause any IMD
problems, not that it is normally much of an issue with FSK modes. I use
exactly the same audio levels as for PSK.

The K3 is rated for 100W output for 10 minutes, so full power should not
cause any problems. The fans will just have to work harder for a living.

I have never used VOX. Why would you need to? If you have a fully wired
serial cable between the K3 and PC then just set WSJT to use that COM port
and in the K3 menu configure PTT to use RTS.
