Hard shifting is a symptom before it happens. Even if you modified anything otherwise, it can still happen.
If you want to know the mod I recommend first. Next Gen Drivetrain Valve Body upgrade kit for the A10. Knowing your car is going to be on the recall list along with mine. Which is to say 2020-2022 Camaro A10's. The upgrade will tell you if you only need the valve body upgrade or a new transmission.
The other reason I brought it up is we are both obviously modified and Chevy and GM are going to refuse to cover the recall in your case, as they already have in mine. Or you might get lucky and find a good Chevy dealer that will do the upgrade for you since GM says there's no fix for it. When there is.
All I'm saying is to keep it in mind. Even if you unlock the TCM and tune it, it will happen eventually. $1000-$1500 now for the valve body upgrade kit, or $3000-$6000 later when the trans blows up? At least check if your car is on the recall list. Then decide if you want to add more power knowing what can happen to the trans.
And to answer your question in #2: Porting the LT2 will yield gains, not porting it does nothing for the 95mm TB you have installed. (Creates a bottleneck so you are no different than if you were running the stock 87mm TB) MSD will yield better gains, especially if you use a 103mm TB instead of the 95. It also allows you to run higher rpm shift points on the top end. Right now my LT2 is ported to 95mm for the 95mm TB, and I run up to 7100 rpm before the car shifts. But the cam I have can handle upwards to 7600+ rpm as I found out when it hit the rev limiter during tuning. You can probably run upwards of 7500 rpm depending on your power band with the MSD and assuming the stock cam/crank can handle those RPM's.
