You're talking about the sway bar links right? What Porsche calls Stabilizer Links?
If so, you shouldn't need to balance the wheels. The wheels are balanced off the car anyway.
It should not change your alignment either.
They didn't even have to remove the wheels to do the work.
But, you say you're getting a +75mph vibration, so something's not right.
It is possible that you lost a wheel weight (or they knocked it off, carelessly). And, as the tires wear, the wheels can lose their balance, so if your tires have some miles on them, either of these may be to blame.
I agree that if it were required, they should have mentioned it upfront. Since it shouldn't be, that probably why they didn't mention it.
