Those are some very good points you have there.
I strongly agree with the not threatening of hell. That's one thing that made me turn away from Christianity. It seems to be based too much on guilt and fear.
If you look at it from another perspective, the concept of heaven and hell is too black and white. If God is all knowing and understanding then he would be able to understand why certain people just can't beleive in his existence and why people have broken commandments for a specific cause. Such as a poor man stealing food for his family.
I guess what I'll do is teach my children about all of the different religions, beleifs and philosophies and then let them decide for themselves.
