Hi,
I want to render an image with a transparent background while keeping the
lighting of my object intact as if there was a background.

You may try using a fake background. It could be a large sphere with the 
no_image and no_shadow attributes.

With no_image, that object remains invisible from direct view.
The no_shadow is to prevent it from interfering with your lighting.
You may add no_radiosity if your scene use radiosity.
That object will act as the background and show in the reflection.
