Your interest in languages is one thing, as long as you realize that most people in the world don't share your passion, no matter how much I agree with you that knowing a language is important. I speak three languages fluently, and have a working knowledge of six, so I can appreciate that.
As for the Greek being the authority, it is by virtue of the fact that it is the language in which the New Testament was written. Its correct interpretation goes beyond words because its syntax and tense are not always equivalent to anything in English (aorist for example).
Instructing people on the correct interpretation is fine with me as long as you realize that this leads to official truth which we Orthodox and Catholic accept, but the Protestants don't. Once you start preaching, you become the "church." And that is contrary to anything Protestant, let alone the idea that the Bible is "perspicuous."
Goodness alive! There are untold numbers of native English speakers in Shanghai! That is why public announcements are in Chinese and English here. There are native English- speaking Americans, Brits, Auzies, Kiwis, South Africans, Other Africans, Indians, Singaporians.
