Welcome from New Jersey here. As for blades, I'm not sure if they are best for the Muhle R41, which I do have (but sits unused due to other razors that I feel perform better), but my favorites on your list are Gillette Silver Blue, Polsilver SI and Voskhod. I have some Feather blades but haven't used them enough to state my opinion on them just yet. Never tried the Wilkinson's.
I have my eyes on Stirlings Vanilla sandlewood as well along with Tobs St James Arko Stick Mickey Lees drunken Goat, And anything from Dr. Jons =]
You’ve got everything you need, but we all know it doesn’t work that way. If you can find a minimalist who’s saved money on shaving in this group, you’ll be the first to do so. FWIW, none of my razors shave any better than a fatboy. By the way, all the soaps you are considering are good ones. Blades? The better your technique gets, the less it matters which one you choose.
