My rule is TCS and VCS on for inclimate weather/road conditions and everything off for dry. I also never "try to induce oversteer" on any road. While fun, oversteer isn't always the quickest way around a turn. Especially considering it is your first RWD car, I'd leave them on for both conditions until you have a better understanding of the different vehicle dynamics between a FWD and a RWD car.
