Welcome to SRP. This is the place to learn about the art of straight shaving. I'm not a mentor but I'll try to give you a little direction.
About razor honing ( And practically everything else)there is excellent information in the WIKI. To touch up a razor all you really need is a lapped barbers hone. People do sell them on the classifieds here. As for a razor, look here in the classifieds also, don't do ebay until you learn more about straights. Spend time here you can learn lots about what make a decent razor. If you have a razor already, send it out to be professionally honed. Again check the classifieds there are Hone Meister's listed there and there is no better way to start than with a sharp razor. Take your time do it right you will love the finished results.
