On the topic of whether an axial tilt change would produce tsunamis, I think that can happen if the axis shift is relatively fast. The ocean water would try to continue moving along the previous spin direction of the Earth.
The C's mentioned that perpendicularity of the Earth axis will be restored (no more seasons) and that the previous 20 degree axis shift was relatively slow.
Another thing that was mentioned is that the comet cluster would pass the plane of the ecliptic of the solar system between 2006 and 2012. Though we do not know how far from the inner solar system that happened. Since it is a periodic comet cluster (3600 years orbit), it is traveling around the Sun.
