Welcome FlameGrilled! :)
1) By this all will know you are my disciples if you have love among yourselves (John 13:35). Sure I know that not all JWs do this, and that people from other religions or non-religious people do this also, but as an official doctrine JWs will NOT kill one another in war, and in general there is a genuine effort to exercise "agape" love not widely found in the world at large.
Can I suggest this chapter?
Matthew 5 2) Preach the good news. Sure I know other religions try to an extent, but JWs are known for their preaching. One might disagree with the details of the message but I don't want to get into that here. They do certainly direct attention to God, Jesus and the kingdom.
What gospel is being preached? Galatians 1 Is it this one? 1 Corinthians 15:1-4
3) Gather together in worship. I include this one since I understand the arguments put forth in Ray Franz's book, but the NT really seems to be clear that some level of organized worship is required "and even more so as you behold the day drawing near".
Who is being worshipped and how? John 5:23, Hebrews 1, Colossians 1:15-21
Blessings in Christ, Stephen
