I think it was just one event (Occam's razor and all). Like Dodge said, those learning pods are probably just standard for Vulcan children (and their human friends) on any Vulcan station with children. Sarek was there during the attack, the only way to save her life was a mindmeld, and from then on they were family more or less.
Almost certainly so.
They had to save money on sets somewhere, but it was a damned confusing place to economize.
