Would you expect this planet to be hotter or colder than earth?
Yes, it is absolutely silly to predict an atmospheric/surface temperature without knowing it's composition or density. And we don't understand the formation process of atmospheres well enough to exclude any type of atmospheres around different stars.

There is however one more or less objective quantity that you can calculate: The equilibrium temperature. That is the temperature that the planet would have without an atmosphere.  

This is essentially given by the planetary distance (which you have) and the stellar irradiation (which you have still to find), and the planetary albedo (a free parameter between 0 and 1).
