Hi Lostinnj83. Welcome to the forum.
Contrary to many, I suggest that you don't tell your JWs anything. Don't show them any outside sources. Don't do anything that makes you appear to be be 'opposing' them.
Be patient and do your homework. When it is time for discussion, you should only ask questions and should only use WT literature for those questions. Do not quote them yourself, open it to the page and ask them to read it to you. Be firm but calm. Ask your question as though you are asking for help to understand. Try to make them feel obligated to answer it.
ONE question at a time. ONE.
Never throw a whole basket of their garbage at them. Just ONE question.
Once you have asked it, you then have to keep them on topic. Make sure you know what their answers are like be before you ask. JWs have 101 ways of changing the subject. Know them all. Know how to deal with them. Don't answer their questions, they ask them to avoid your question.
Remember don't tell them anything. e.g. don't tell them to stop bullying you into believing their answer, ask them why they are doing it? or How do they feel about that, or What would they say if a Catholic behaved like you are to bully his wife/daughter/mother into believing the Trinity? Act offended that they are using whatever technique they are using when they publish articles slagging off other reigions for doing the same.
Google Watchtower Propaganda and read the hits from watchtower.org and memorise any tactics that they might use on you so that you can easily take them to their own official website and ask them to read a paragraph that attacks other religionists for doing exactly what they are doing to you.
Good luck
Chris
