Before learning it, do have your riding basics down. Meaning you are very comfortable riding it around and doing kickturns and not be pushing mongo. Best to learn it whilst stationary with your wheels on a crack so that you don't move and slip out so much. I don't recommend doing it on grass or carpet cos when you pop the tail, it's gonna be absorbed by the floor and when you start doing it on pavement, your muscles will memorize a different way of doing it. So nope, no easy way out i guess.
To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.
