Welcome. There are many inconsistencies in the bible, to believe that it is some perfect and cohesive narrative is simply wishful thinking, don't fall for it.
The Watchtower likes to selectively quote scriptures, even parts of scriptures, followed by a lot of conjecture, it can get confusing, so be sure to read everything in context. Most of their beliefs don't really hold up once you start to question things, so take nothing at face value, look for the logical inconsistencies. When it comes to the history and beliefs of the Watchtower, verify everything using neutral third party references, like Wikipedia. They lie about their history, and they don't tell people some of their more disturbing beliefs until they have studied for quite a while, so be wary.
They also use cult mind control techniques, like controlling your time (hours of meetings everyweek, obligatory door to door work, etc., controlling who you can talk to (ex members are shunned, friendships with non JWs are discouraged), and they claim to be the only path to salvation, all others will be destroyed by God at Armageddon, which they believe is eminent.
But since you are already questioning things, I am sure you will figure all that out for yourself.
