Does the speed of a planet going around its orbit or the speed its spin affect its ability to support life?

I would say yes. In the extreme case: 

If it's tidally locked to the sun, like the moon is to earth, then the two sides would be temperature extremes. The terminator, the edge between the sides, would probably suffer extreme atmospheric events. The dark side may be cold enough to freeze the atmosphere. These things should make life more difficult.
