Jaffacake, thanks for your thoughts.
Yes the bible does indeed refer to other Gods, as you surely must be aware of, however, there is only one 'true' God, ie, the almighty creator, the Father. All other 'God's' are inferior to the one true God, the Father. It's quite simple really. So it is ok for Jesus to be called a God, Theos, but it is a stretch to say that this means he is the one true Almighty God, the Ho Theos.
As far as the huge emphasis on Christ in the NT, that is understandable given that it was in the first century when Jesus appeared and that most of the early disciples were Jewish converts who already knew full well that God was one, their Father, YHWH. They did not need convincing of who God was, just convincing that Jesus was the saviour in whom they needed to put their faith, rather than continued works and obedience to the Mosaic Law. Interestingly, in Acts 17,in his speech to the pagans at the Acropolis, Paul made the main subject of his speech the creator, God, because those listeners needed to know who the one true God was. It was only towards the end of his speech that he mentioned Jesus, a man.
I agree with you re JW's emphasising the OT far too much and not putting enough emphasis on Christ. JW's rightly render sacred service to the Father, but they have gone too far and have adopted a kind of pseudo Jewish type emphasis on Jehovah. The JW religion revolves around two main things: Jehovah, the Father (commendable) and the Watchtower Society (lamentable). They thus honour their own leadership and organisation more than Jesus.
