Is there a way to change a regular road to a two-lane, one way road or vice versa?
Is there any way to select a stretch of road itself to get info on it?

No you can't. The direction of the one way road is determined by the start and end point when you build it.
I wish they provide us an alternative way to switch one way road direction.
The mod that cordo links to is just the thing you want - You will be able to drag the direction of roads to upgrade them to one ways.
