Your main job I would say is to check yourselves if this really is the truth or not. Certainly if you get baptised you will be welcomed with open arms, but then in the future if you realize that actually this may not be the truth, they will avoid you like the plague. Even if you just question one doctrine you will be treated coldly by your fellow witnesses.
So do yourself a huge favour, check out the orgs history. Have they proved to be totally trustworthy or have they in fact been misleading people for decades? But you must check others views not just JWs as they will be totally biased.
I wish you well and hope you will come to the right decision and enjoy the rest of your life.
