Do some serious study about the theory of tailwheel flights, and ask your instructor about any uncertain points.
In particular, think about -
* How to taxi when you cannot see over the nose.
* Memorise the taxi attitude as it will come in handy later when flaring.
* Control positions whilst taxiing with various headwind/tailwind and crosswind components.
* Gyroscopic precession and Assymetric Advancing Blade effects, and again how crosswind can help/hinder.
* Possibly opposite rudder inputs from previous types.
