Yes, you are correct. BU is Segwit plus 2mb blocks. While BC is just segwit.
Yes, BTU has a lot of support 1)from miners, 2)those that are sick and tired of high transaction fees and slow conformation,3)those who have businesses that use bitcoins.
You have nothing to worry about. Everything will be fine. Just sit tight and enjoy the ride.
