The better the FRFR monitors are , the happier you will be with your tone . There's a pretty big difference in them.
(1) Support page on Fractal site has the presets up to download , download and install Fractalbot to install them on your unit.
(2) No recommended settings I know of , I would suggest approaching advanced settings as you go , just play with them and familiarize yourself with the changes they make one at a time , I find I don't use them a lot personally.
(3) Probably the best free UR IR's are the ones Fractal has in the AxFx Mk II firmware download .
