The blood type O means that there are no A proteins or B proteins attached to the outside of your mom's blood cells. Your dad's blood cells have both A proteins and B proteins. Since each of your parents passes down one gene for blood type to you, your mom just gave you the smooth O cells. Your dad could either have passed down A cells or B cells. You ended up with a B from Dad, an O from Mom and a + from both. Makes perfect sense!

Yes, it can happen. Every person has two genes to determine their blood type. These genes can be A, B, or O. A and B and codominant and O is recessive. So you only have type O blood if both your genes are O, you have type A or B blood if one of your genes is A or B and the other is the same or O, and you have type AB if one gene is A and the other is B. So your dad has an A and a B gene and your mom has two O genes. Your mom has to pass an O gene to you and your dad can pass A or B, so you and all your siblings should have A or B type blood.
