The setup should be fine. the reason why they said to re-torque your wheels is because with any after market setup the general rule of thumb is to tighten them the first time, go out and drive it around in hard turns then come back and re torque. as for whether this is actually useful, well its more of CYA then anything else. if your feeling a vibration then they probably weren't balanced right. are they chrome? if so them it is possible that the rim could have moved inside the tire right after they mounted them. Ive had that happen to me before when I mounted a set of foose wheels and they moved inside the tire after I drove off. reason being is that the place where the bead sets is also chromed so its very slippery, and the tire mounting lube doesn't help the cause but its a necessity when mounting low profile stuff. so put two and two together it is possible. it could also be possible that the place that mounted your wheels just didnt balance them right, but hope that helps.
