Jerky at low RPMS

It took me awhile to adjust from the 350Z, and I had lots of issues because of clutch pedal "play" (funky engagement point) and clunky shifter.

I don't see it so much as that for me. Even after I've fully engaged the clutch, and I'm in first gear accelerating, say from 2500rpm up, if I do it slowly and smoothly, the car jerks/bucks slightly once or twice (not really a large buck, but it hesitates and the RPM fluctuates slightly). It's weird. It almost seems as if the electronic throttle is modulating up and down a few times.

If its uncontrolable then it needs to go in for repairs.

Understood. Magazines gripe Z/G having an on/off abrupt feeling with the clutch engagement.

When you release the clutch in 2nd gear too slow or fast will be abrupt. This is where you need to pivot your foot (ankle) back as you let out the clutch so it doesn't engage too abruptly. It's hard to describe. Let's say the ball of your foot is on the floor when you start in 1st. When you go to 2nd, lift the ball of your foot a few inches off the floor and quickly and fully press down the clutch pedal with your toes, then engage 2nd, and pivot your foot back as you release the clutch pedal before applying gas.

Pressing down the clutch pedal quick before easing it out seems to smooth out the engagements regardless of RPM... and I can get things smooth and fast as low as under 2k RPM.
