One other small thing that might help is pulling your stick all the way back to "lock" your tailwheel (if you're flying a tail dragger, of course). This really helps with stability during high speed taxi at the cost of manuverability. I use it almost always on landing, and when you are trying to get to a rearm pad, it can help keep you from an unintended excursion through the weeds. When you get slow, and really want to turn on a dime, just release the stick.
