Hello, Straight Razor World!

I recently decided to switch to the straight razor and, since I live on an underdeveloped island in the Caribbean, I had a visiting friend bring a razor and a strop from our home town. He brought me a rusty, but functional, Erik Anton Berg, Eskiltuna, Sweden razor and a "Genuine Shell" strop with the silk finish strap on the back. I have a wet stone (not sure of the grade).

My question is, with the limited resources I have listed, can I adequately prep the straight razor for my switch over? I'm going to have to make my shave cream at home and not sure what I'll use for a brush; but I'd LIKE to be able to start sooner than later.

Any and all advice you may have would be greatly appreciated.

Thanks,

Nic
