Welcome to Nikonians! For shooting action in low light situations when flash is not allowed "Fast Glass" is the price of admission. If you are shooting at the wide end of your 55-200mm the Nikkor AF 50mm f/1.8D, 50mm f/1.8G AF-S are the least expensive options. The AF 85mm f/1.8D or 85 f/1.8G AF-S provide a little more reach for about double the price. The AF 80-200mm f/2.8D ED or the Sigma or Tamron 70-200mm f/2.8 lenses would be next if you need the versatility of a zoom and or the additional reach. Good Luck and Enjoy your Nikons!
