Wheelies are manditory for some tailwheel types and also helpful in crosswinds for others, best to get it on the ground and under control. In Tailwheel crosswind landings, holding off for a 3 pointer could see you drifting off the runway then having to use rudder to get back on the runway setting up a groundloop?
Wheel technique roughly is flare but do not hold off, let the mains touch and as soon as you hear the squeal push forward on the stick to keep the tail up (nail it) if you don't keep level as soon as you touch down the Tail will drop resulting in a nose up attitude and small lift off with no airspeed and then back down in what then becomes a series of bounces that increase in size "hopity hop down the runway".
A good Instuctor will demonstrate and teach both landing techniques until you are totally competent. You will then have the most important tools to fly a real aeroplane
