Only just found this thread. This was my patch too until a couple of years ago when we moved. Your list looks pretty similar to mine though I never saw barnacle geese (and a few others). Arctic skua should be pretty easy about now if there's an easterly wind. Listen out for frantic sounding sandwich terns and keep a look out for anything flying fast and purposefully. I also saw quite a few bonxies and single pom and long-tailed there too. Manxies should also be doable around now but normally a long way out. I also saw black-throated and great northern divers but neither often. In spring, listen out for grasshopper warblers in the gorse about 3/4 of the way to Kinghorn and occasionally just up the slope from Seafield tower. The other bird that springs to mind, other than the black redstarts which stayed for months and were incredibly obliging, is that I saw quite a few woodcock when there were proper cold spells (coming in off the sea?).
I hope you enjoy birding there as much as I miss it!
