Just using 3ds max is only going to make your efforts more complex. Artlantis Render/Studio is easier to get started with. Both can create very good renderings.
But I suggest to stay inside ArchiCAD for a while, before you add in other applications.
The problem with additional light is that you will have more really white spots, without any detail. It might be better to play around with Photoshop to improve the image (try the levels adjustment). The lighting model in ArchiCAD is a bit primitive (to say the least).
