Hi faceoff3001,
1) No, this is currently not possible.
2) Yes, if you apply effects to a clip, select the place on the time line that you want to render as an image, and then go straight to the Photo section to render it.
3) Lumion currently requires that the window is active while it is rendering, so if you switch to another program, Lumion will pause the rendering process.
