Welcome Addagirl.
You are doing the right thing. Checking out an organization before you join. Your study conductors should know and encourage you to check things out for yourself. I once used the example of reading several movie reviews prior to seeing a movie - would I do less when possibly changing my religion?
Of course, they don't see it that way.
If you come up with too many questions or material they view as apostate they will try turning you over to a more mature study conductor and finally you'll be dropped (you're heart condition must not be right at this time will be the likely excuse).
I wish you and your husband the best of luck.
My main pet peeves were:
607BCE for Jerusalem's destruction
Confession to men and judicial committees and the secrecy involved (plus the non-biblical reasons that can be used for disfellowshipping someone)
