Habitability:
If humans lived on Mercury they would find an environment similar to the moon. Mercury is airless, part of the vacuum of space. Mercuries temperatures range from 700-100 Kelvin from sun to shade.
Travel:
The most recent spacecraft, the MESSENGER took over a year to reach orbit of mercury., while the Apollo missions took about three days to reach the moon.
Terra forming:
Very Expensive, and many problems to account for. Some problems are: solar radiation, water, oxygen, and heat.
To combat the heat and radiation, you could could use solar shades (very expensive and untested), and nitrogen from Titan (very far away) to cool the very hot and unsafe surface. Water may come from icy comets (which would require a lot of work to do). Oxygen would have to come from an alternate source or . Traditionally you could just build domes. Chances are very low of future human colonization.
