Sparkly, I would say, as a BT myself, that going to Chabad may not give miamilawyer what he/she is looking for as far as the true emuna in Hashem that is the necessary stepping stone for keeping mitzvos.
My sisters became BTs thru Chabad and wanted to persuade me to join them in the “good life” by talking to me about the neshama and how it needs Torah and other gobbleygook that appeals to some people who might be the searching type.
I, on the other hand, was not actually search, but Hashem must have been searching for me in some way or other, because I found myself at a seminar weekend put on by Aish HaTorah for their Discovery program. It was there that I learned much about the truth of the Torah and that it is divinely written. Their program is much more intellectual than many of the classes given by Chabad, which appeal more to the emotional side of a person, which did not really motivate me.
But once I had started to learn that there is truly Hashem in the world and that he made us and wrote a book (just a beginners thoughts on the whole religious world that I had at the time) on how to live our lives, then I understood that it was my job to figure out what to do and how I was supposed to do it. It wasn’t so much of a choice to me anymore because Hashem’s existence was so obvious to me at that time. I was fortunate to take that motivation and turn it into a life surrounded with Torah and mitzvos.
I will say that unfortunately, many MO teachings do not really give the full depth of written and oral Torah and leave the kind of gaps I think you have, which can make a person be wishy washy in their beliefs and observance. Once you strengthen your understanding, you might have a whole different take on the arguments.
