2 and 3 are dealt with by the heat cycling. 1 is kind of interesting,
but I've never heard of it as a concern in autocross; only drag racing
where you have low pressures and high torque. I suggest you mark the
tire/rim, drive normally at the event, and see if it's an issue. I
don't balance autocross tires anyway.
