Any and all of these things make sense, however most are subject to scheduling and time restrictions.
One very important thing you can do here and now is to find a large space, empty mall parking lot, etc. and without going nuts see how your car reacts to sudden, not extreme, throttle inputs, letoff, steering inputs, corrections.
The point here is to gradually explore what upsets the car, what looses traction without extremes, where you can gain a feel, without traffic and large stuff to hit.
It is the cheapo alternative to schools that teach slide control/correction.
It is a nice, controlled methodology to help you when and how sudden things happen.
