The biggest mistake you can make is ramming the throttle open like you may be used to with a tri-gear. Advance it slowly, and just be ready to use rudder. They really are no harder than tri-gear setups, maybe even easier if you remember to use your left thumb. They are less prone to warping out or shape and assuming different tendencies every flight like nose wheels, and I have even set up a trainer as a tail wheel and the student had no trouble learning that way.
