2. I turned it on toward a wall behind me?
3. I shone it out the window of my craft? (Would it appear to bend in one direction or another?)
4. I shone it toward the floor?
As long as you are traveling at a uniform speed, that is, not accelerating, the answers for your frame of reference are:
1. The light heads towards the wall at c.
2. The light heads towards the wall at c.
3. The light heads out at c with no bending.
4. The light heads for the floor at c.

4. The light heads forwards at a slight angle to your direction of motion at c, ultimately hitting the floor.

I know it sounds weird, but that's the way the geometry of spacetime works.
