I think the hardest thing for me to get used to when I switched to Nikon is the AF modes. I guess for track you'd want to use the continuous af mode. You can also choose if you want to manually pick the AF point or have the camera do it. Then there is the iso setting, I've found the auto setting pretty useful as you can customize it somewhat. If you want to pick the iso you should have no problem shooting up to 6400.
