What i have in my trans is the least of what you should do.
No, the 300M is not overkill. I personally think you should do it right the first time and never have to touch the trans again.
Do the 300M, since the 4340 is known to fail on a decent size supercharged build. If the 300M is out of the budget, at least do the 4340 to give yourself more wiggle room.
The ideal trans build would include, 300M, all Valve Body upgrades, TransGo Shift Kit, Hardened 4th, 7/8th Chain, but its all about how much your willing to spend in the end.
In reality though, its your foot that kills the trans. You plan on beating on the car? Think about upgrading the trans.
