Your request for a such a hub is sound and shows a right heart, but don't get hung up on semantics. God's most important name is Father or even Daddy. The importance is in our relationship to the most loving Being there is.
God's many names are but facets of his infinite and eternal nature. My own dad was a fishmonger and poulterer, but I never addressed him as 'Fishmonger', I called him 'Dad'.
Knowing the names of God should be a desire born out of a deep longing to know more of him, not some technical theological exercise.
When Jesus was asked to show us his Father, he simply replied, 'If you've seen me, you've seen the Father'. On the other hand he castigated the scribes and Pharisees who despite searching the scriptures minutely failed to see their own God in their midst. Don't do as they did and 'strain at a gnat and swallow a camel'.
Paul wrote that the Father has given Jesus the name above every name. Read it in context and you understand that name is Yahweh, which is shared equally among the Trinity. But it is the God of the name and not the name of God that transforms lives because Yahweh is incorporated in Yeshua anyway.
My name is Allan and, although I am her husband, Allan is the name my wife uses to address me directly, even though 'husband' would be a perfectly proper and accurate name for her to use.
I may write on the difference between the Old and New Covenants because it is clear a lot of Christians are unclear of what the difference means. Suffice to say for now, God is not out to get you or hammer you for calling him by the 'wrong' name. Check out Isaiah 9 which tells us that Jesus is also known as 'Wonderful, Counsellor, the Mighty God, the Everlasting Father, the Prince of Peace'.
What gives God the greatest pleasure in hearing you speak to him is not some technically perfect performance of a name you read in some theological book, but 'I love you Daddy'. If you can learn to say that and mean it, he won't care a jot for whatever else you call him.
