You look like you're on the right track with the Solingen blade. A Sharpie marker and magnification are your best friends as you're learning to hone. It takes time and practice to get good edges.
I think that either Vaseline or baby oil will work for humidity protection, but I have never used any type of oil and haven't have any problems with rusting. Unless you live in a tropical jungle or are storing razors for years, you're probably fine to just make sure they are 100% dry before putting them away. If you see any rust developing you can polish it off with metal polish before it becomes a problem.
I used to use lapping film and diamond pasted balsa to keep my edges fresh. It worked well. I had 0.5um, 0.25um, and 0.1um balsa but have never tried any Crox pasted strops. Going from 1um film to 0.1um balsa seems like a big jump, but the Crox strop in between them might bridge the gap. You'll have to try it and see how it works.
I have some non PSA lapping film at home that I can send you, PM me if you're interested. I have several grits, from 30um down to 1um.
