I think you have some really interseting questions. Particularly your question about the social groups who used Caligraphy sets. I suspect there’s a lot of research you can do on who was literate in China. Also, you can research the cultral impact of having a trading system in which many different languages were spoken. I think all your questions have the potential for in-depth research, but you need to make sure you do that research. For instance, when you learn about the price of producing a caligraphy set, make sure to research its materials and how it was made. All and all, I think you have excellent questions that will lend themselves well to a paper, since they are all inter-connected.
