Snapback goes with experience, I think its largely tied to not having enough wheel spin through a corner, but I haven't really dwelled on it enough to confirm this, but for me it just faded away the more I got sideways.
Not really. Softer rear suspension and stiffer front means that the tail can moves much more easily. Stiffer the suspension, the harder it is to turn.slightly stiffer front suspension/sway bar and a softer rear suspension/sway bar can help reduce the violent snap.

OP, what you want to do is increase your your camber angle and toe angle on the rear. And then stiffen up the spring till you feel that its more stable.
