if the light wasnt as bad as franglais described, i heard that fuji 800 pushed to 1600 looks better than actuall 1600. but, as he said, if its so bad that you need a couple more stops, then pushing the 1600 may be the way, but just know the shots are gonna be grainy. I may have missed this, but do you have a tripod? This may help you a little bit. You can't set the shutter too slow without blurring the action, but maybe a little slower than you could handheld.
