Any Ideas?

So we- as in Ben and I- are hosting Thanksgiving for my parents, Ben's parents and Ben's two sisters (my brother is staying in Cali). While I think I'm a pretty good cook (when I try), I don't really do it that often.
We are making the main dishes: turkey, stuffing, mashed potatoes (Ben's specialty) and the gravy. I love traditional mid-west cooking so my ask is: anyone have any good, classic recipes for those dishes? Lemme know!
