Diff between a TBD and a LSD?

Well, you're not braking only in a straight line if you're out there on the ragged edge. So figure in the sideways weight transfer, and it will be pretty clear that a mere bias adjustment rearward can make things incredibly tricky.
On point 2, braking that hard into a corner on the street? Let's put it this way, say I'm running to my capability in the yellow car on track (~2:00-1 at Thunderhill), if I dial it back say 4 seconds/lap (passenger pace) I'm probably in the mental state of being able to carry on a conversation, text, eat, whatever. Comparing that to aggressive street driving would probably equate to a 2:20 lap. And at that point you aren't even coming close to anything the car is capable of, braking and cornering-wise.

I have had the alignment with kinematic toe done by a reputable local shop. When I replaced tires recently, they had very even wear and the tech said that meant my alignment was good. With that said, could I still have an alignment problem?

...with your adjustable sway bars. If it starts to push...just back off the gas a bit, until you can make an adjustment. I have not done it in so long that, haven't need to...so either I have it right or my LSD (ZF with Guard disks) is no longer working....
If my car were to understeer (Maybe it does a bit and I drive around it), I'd try to dial it out with the rear bar, set it a little softer as I recall. The stiffer the rear bar the more over-steer...so the reciprocal seems logical.
I'd never give away my trailing throttle braking...even if I have to rebuild the LSD...it costs <$1,000 to rebuild it as I recall. The Weissach LSA on the 993 seems to love a clutch pack LSD....that's what the big boys use.
