I was wondering if its possible to connects my CDJ1000mk3's AND Traktor to the DJM 2000 at the same time.
Yes!
The way I want it set up is...
Yes!
ALSO is it possible to ... switch between CDJ and Traktor virtual deck.
Yes! Just change the channel input from USB to LINE or DIGITAL.
How does this work with Traktor set up digitally into the DJM 2000??
The DJM is your soundcard. This video gives you a bit of a start on the audio configuration, but instead of setting it up as a 6/2 device, set it to 8/0 (no inputs).

Do I have to map the pads on the touch screen for cue/play and what about the pitch control etc.... how can they be mapped???
Yes you can, just go into the software and start mapping the input controls, I don't have a vid for it but it's not too hard to figure out once you watch a couple of videos already available online for it. If you need further assistance, let us know.
