here are my thoughts G after reading the specs

question1
after reading the specs i think that's all you are going to get, because after the second shot it drops out of that mode and you propably will have to reset

question2
indoor lighting without a flash handicaps you coming in the door, in order to shoot action shots you need a fast shutter speed which in turns means plenty of light. the ISO can be changed to help ,try setting it at 800, take a few shots and judge, then start dropping the setting to see where your best results are.I have not seen the building your in so you should do a few things next time you are there, look up at the lighting and judge where they are pointed and try to shoot from the brightess spot you can get to, if you can get floor level and kneel down and shoot upward towrds the lights you may can cheat enough light in to make it work but you might have to also edit the pic in photoshop if the light shows up in the pic but thats better than no pic at all. you are a smart fellow study the room and just try to get in the best light even ambient light will help, if they would let you use flash...proplem solved hope this helped if it don't take me a pic of the arena and let me study
