Is there a such thing as too many items?

My fiancé and I are registering. I'm starting to wonder whether we're looking like we're getting greedy by putting too many items on. We have the "appropriate amount" for the amount of guests, according to Zola, but we are registering for two sets of many items, as we are keeping a kosher home, where you cannot mix meet and dairy. That means that we need two sets of plates, utensils, some appliances (spatulas, pots and pans, knives), serving plates. Am I overthinking this? Will people just buy what they will and we're giving a good variety? Thanks for the input!
