RE: Tail dragger takeoff
You shouldn't have to push forward on the stick at all. Hold up elevator while you taxi, it "pins" the tail down and makes steering a little more positive. Whwn you line up for takeoff, release the elevator, and as you throttle up and begin your roll, be prepared to use your rudder to maintain your heading down the runway. Depending on what you're flying, the tail will come up on its own after you have some forward momentum, or when there's enough propwash over the tail.
If you have a plane with enough downthrust, the nose will tend to dip and you will need to "ride" the elevator to keep it from over-rotating and flipping over or just hitting the prop.
Once the tail breaks ground, you will need to be on the rudder, feeding in 'right' to counter P-factor and torque reaction, which tends to make the plane veer left. Crosswinds will make the plane weathervane, or turn into the wind, if the wind is strong enough.
Two trains of thought as far as I am concerned for takeoff:
1- nail the throttle, hold some 'up' elevator and get it off the ground quickly, to minimize how long you have to fool with keeping it straight until you have sufficient airspeed to fly. Downside to this is, when you suddenly go to full power is when the plane most wants to hang a left, and it's sudden, so you have to be ready, and practiced, for it, or you're likely to torque roll into the ground as you lift off, then you have the additional thing to think about, countering the roll with ailerons.
2- roll the throttle on gradually, feeding in rudder as needed to maintain heading, the tail will come up, and as you build speed, gently ease back on the elevator and the plane will fly itself off, your focus can remain on rudder input to keep it straight. Plus, if you start to veer to one side or the other, you can back out of the throttle and abort the takeoff.
I'm a big fan of #2. It takes some practice, but if you've got the basics down from flying tricycle gear, you'll get it pretty quick. Start practicing with slow takeoff rolls, see how your plane reacts to throttle and how much rudder you need, and as you get faster, you'll eventually take off without realizing it, and viola! you're flying.
BTW, all my planes are tail draggers, and my first one was a Cub
