The first one would be the easier of the two in my opinion. Just use the generate>beam effect. Several layers with the beam effect applied with a bit of stylize>glow on the layers themselves and the appropriate amount of glow added over top for some light spill over the actress should get you close to the desired effect.

RoRk is correct, the Beam Effect will work.
To help you set it up in perspective create 2 solid layers, apply Grid and adjust settings to taste.
Make 3D and rotate 90 degrees in the X axis and pull one up and the other down. Use the grid lines to align the animation of the Beams. Each beam will be a separate layer.
