Another thing that I couldn't find out yet is how to make the reflection in the wooden floor smoother. Is there any setting in the reflection layer (or any other) I can change to make that happen?
Yes, you should reduce the "glossiness" value for highlight and reflection to something like 0.75 or so. Then you need to up the reflections subdivisions to something like 24 or 36 to keep it smooth (otherwise at lower values it gets grainy)
