I think we'd be better off working incrementally on larger and more sophisticated space habitats. Work our way up to O'Neill cylinders and the like. Much easier to harden a space habitat against radiation and to provide air, water, and power to it than it is to terraform an entire planet. Still not easy, though. Edit: Much easier to move out of the way when the Sun expands into a red giant, as well. Not that we have to worry about that for a while yet.
