I develop family names first and went for a simple approach of naming families after geographic features. Then I decided given names as far as 'wish fulfillment' on the part of parents for their children, and (in my world), courtesy names based on the perception the young adult has of themself on their movement into adulthood. Epithets are all poetic-ish, and I would do more reading into poetry as well as the four classics before continuing to develop art names or other poetic epithets-- I don't use such epithets myself very much. I look up characters and then run the names by two different Chinese speakers along with the 'seed' of the idea behind their naming, and they tell me if the point is getting across. Repeat until your cast of thousands is named.
