either priority works, actually. in a dining hall or ballroom, u can either set ur f-stop to the smallest number possible, or shoot with a low-shutter speed. choose either option, and the cam will decide the rest for u. reason i suggest Av mode is dat it takes the 2nd-guessing of wat is the right shutter speed out of the equation. its a personal pref. watever works for u, go with it.
since u got some time at home, try it out first b4 deciding which one works best for u? also, go earlier to the dining hall and play ard with ur cam. then u can set ur cam up properly.
as for flash, most probably ur cam will auto-fire ur flash, since its low-light. if ur cam got a red-eye reduction function, use it. this will prevent ur subjects having those ugly red-dots in their eyeballs.
