I'd say full silver rings +1 (since they give you the most acc, cause you can wear all 4 of 'em) and seafood dishes give the most acc. I use Mugwort Carp, they are lvl 40 so difficult to get your hands on usually, but it's the best. Here is a list of some of the accuracy foods! I don't miss any more than all the other DoW classes do, I use a Vintage Bill, rank 50, with 130 Dex. Hope this helps!
