1. looks like you already have good razor, but you need to send it for honing to someone. You can find someone near you
Member Services - Straight Razor Place Classifieds
Also you can find some great vintage shave ready razor in classifieds.
Or you can purchase new razor from SRD or other vendor (look at vendors section)
2. I use l'Occitane cade aftershave balm, you can also try Proraso pre/after shave.
3. Personally I don't like Williams soap, but it's cheap so it worth to try.
4. Illinois strop must be good
5. I'm never used arkansas stones, but I heard good feedbacks about them
