I really want to believe he'll get anything of this accomplished in the next ten years but he's missing a lot of specifics. What about radiation? Bone density loss during the trip? If the spaceship goes back to earth for the next trip what do they build the habitats out of?
For the last one the plan is to send fleets of cargo modules and human transports. It won't be one ship going, but 100 at a time untill there's a sufficient base of operations on Mars.
