It's a good question that one can attempt to answer in many ways.
Biblically, sawthelight is correct. Yahweh is the correct pronounciation. You can verify this in the encyclopedia judaeica and the catholic encyclopedia. 'Jehovah' is a later invention by a catholic monk. I forget the date. It could be like only 400 years ago.
Biblically, yahweh is jesus. This can be seen by comparing isa 44:24 yahweh emphasises that he made everything by himself, with the new testament descriptions of jesus\logos. John 1:1 and coll 1:16 exclaims that jesus made everything. So, the conclusion is very simple.
If you want to let god out of the bible, so to speak, then consider what francois has stated. Taoism is interesting in its study of 'god'. Tao means 'the way'. This is interesting because the movement that jesus started was also called 'the way'-acts9:2, 19:9, 22:4, 24:14- at first. Paul and his followers came to be called 'christians' first about 40 50 years later-acts11:26. Contrary to popular opinion, jesus did not start christianity.
