Activity for Nakita

Wondering what kind of food should I serve at reception it's on a Sunday and Reception will only be 3 hours long

I am trying to figure out would it be tacky to have a ipod playing our wedding music and have someone in my family control it instead of having a dj because my guest list is only about 50 guests

My Wedding and Reception is at the same location in the same room and ceremony will be about 15 minutes long 3pm-3:15 pm so reception will be from 4pm-7pm so im trying to figure should I do first dance and father daughter dance before or after...
