He also gives a helpful explanation in the comments:
The imperative form of "go" is:

가 (intimate)
가세요 (standard)
가십시오 (formal)

"간다" and "갈 거야" are both future, and 간다 is used in situations like you are getting up from your seat and saying to your friend, "I'm leaving." and you say 갈 거야 when you want to say "I'll go."
And another:
"마음 먹다" is to make up your mind - now that you mentioned it, it sounds funny hehe. But it's very commonly used in Korean.

터 and 참 are interesting little nouns to know, and 터 means a place, and 참 means a moment. so 갔을 터 = a place/situation that I would have gone (to), so it's used for supposing a consequence of something that didn't happen yet, and 참 is a moment so it means "I was at the moment of planning to go"
