Hi there,
Responding to your 3. question....while JWs are very strict, I have to say, based on my experince being in different congregations and reading about others on this forum, there are many veriations as to what is allowed or considered okay behavior depending on the local body of elders and the culture of the congregation. For example the dress of my first congregation was very formal and dressed up, but I would have been VERY out of place if I wore the same dresses at the last congregation I attended. It depends on that local cong for many "rules" about what is considered okay entertainment. There have been many times I would read about folks getting into trouble for listening to rock or heavy metal yet it was okay to enjoy that kind of music in my congregation.
I was a "born-again" Christian prior to becoming a Witness, and I found, overall, that Jehovah's Witnesses were less strict than most Mainstream Christains.
