The point here is that the best thing to do, based on several peoples experience, is to either a) Get the razor you already got honed to a true shave ready state or b) Get a second truly shave ready razor. Either which you choose you will be sure to have a razor that will work as a benchmark when you practice honing, and you will get to know how a "real" straight should be like.
This way you can focus on stropping and "light honing" i.e. keeping the edge shave ready on a high grit stone.
If you on the other hand is determined to keep trying to hone it yourself (and I don't say you won't get it to shave eventually, but there is a risk of ruin the blade), a 1K stone is to reccomend to ease up the bevel setting process.
Anyway you choose, as long as you are going to hone a razor, whether it be just maintaining the edge or a full progression, lapping the hones and making sure they are completely flat is of great importance, if they're not you will get bad results.
