What about using the photoshop psd file exporter in the image filters? This has a place to export the reflection color.
If you need an alpha, under render options mark save alpha give that a different name than the one your using for your image, change the render frames to one image instead of 60. then press F10 to render scene. Now you have a seperate alpha you can load to use with your image.
To save an alpha with the image in a single file, you must select a file format that is 32bit. TGA seams to work the best. Some formats that say 32bit don't allways work, so you need to experiment. It may depend on the software that is importing the alpha, as some software is not really up to spec when using that format.
