For start location, paint a waypoint nearby with the exact location and orientation required, then jump the PC to that location OnClientEnter. This happens invisibly.
You could always use the adjust position method mentioned earlier but instead of using the Bearing numerical entry just use the dial with the red line indicator in the Orientation section. Click and hold inside the box containing it. You can now drag that red line to wherever you want the facing of the placeable to be. Once the facing is roughly where you want it, you can then make fine adjustments with the Bearing up/down box. To test simply click the Apply button.
