The only one of those that I think are really desirable on an NA car that will be driven mainly in good weather is ABS, and it isn't and absolute need.
My NA has the limited slip, but its main contribution is tire squeal in tight intersections. You can also add it if you really want to by changing out the axle.
My NA does not have Stabilitrak, and I have never missed it. Read through the early forum threads and you will find that all of the "real" drivers would turn it completely off as soon as they started the car. After all, "nanny controls" were only installed by GM to limit our enjoyment. My RL has it, it stays active all of the time, but I can't stay for sure that it has ever done anything.
I like ABS, but we did survive for almost a century without it. Between my two cars and a combined 150k miles of driving on mainly back roads, mine has activated once.
Given your stated plans for the car, I would not let lack of any of these slow me down.
