Hi Lenny,
All of us were at one time over whelmed by this basic idea that the "Truth" may not be what it claims to be. And in your case you have the additional issues that revolve around your family and personal life to factor in, which isn't easy. However, the best advice I can give to you, is take things slowly and just focus on one problem or situation at a time, just to keep your sanity.
Questions on the various doctrinal issues is easier to solve that you think too. For many of us have found that just by reading older magazines and publication of the Society, has helped us to see that most of our religion has been created or formulated from opinion rather with direct scriptural authority. But fortunately, there are so much online resources to help in this regard ... you just sort of know where to look. It quite amazing how much effort other have gone to assist others in this regard.
In conclusion, when doing your research, just post a quick question here if you get stuck. As there a lot of guys here that can help you out in give you various ideas or articles to think about.
