I agree there's no way to know if it's oversteering or not, but imho it's not really relevant.
Focus on the actual problem which is the driver sensation:

Ride heights, bump stops, spring rates, damping, wheel weight, tire size, tire compound, tire wear, tire pressure could all be causing the issue or help in alleviating it.
Regardless of actual handling balance of the car or if traction control is on or off, the car doesn't feel good and I think anyone would agree the OP is describing a problem worth solving.
Alignment is good provided everything is tight, the printout looks like it's from a good local alignment shop that should have checked all that, but that doesn't rule out potential problems though.
There's also the possibility that as the OP has grown comfortable with the car they're driving it more aggressively and you're simply asking the car to do more than it's capable of doing given the tires it has and the road quality. Adding gas while turning = back end slides out, even at moderate speeds. The joy of decent torque available at ~3k rpm.

OP got an alignment and posted it in the very first post. He needs no further parts to achieve a good street alignment and the numbers look good.
Bounciness has to do with damping, not spring rates or preload. You can make any spring on any car feel not bouncy with the right damper tuning. You can also make it feel like a pogo stick on each corner with a bad damper.
In OP's case I suspect a ride height that is too low is causing excessive bump stop usage which means the effective spring rate is too stiff for the damper, softening the damper just makes it bouncier.
