Reply to Help: CDJ 350's with Traktor

Hi everyone,
I am new to djing so this is very complicating for me.
My friend let me use his copy of Traktor scratch pro 2 but i do not have an audio interface. I have been trying to set up my cdj 350's and behringer ddm4000 mixer to traktor, so far i have been able to import the mapping file and most of the buttons and controls on the cdj's are able to control the software (pressing play on the cdj's plays the track etc), but i have run in to 2 major problems.
1. the jog wheel only functions as if the cdj were in cd mode acting as a pitch adjust and i want to be able to use it in vinyl mode to scratch. I am starting to lose faith in that scratching will be possible without the audio interface.
2. this one is much more important. the audio from traktor only plays through one channel on the mixer, I need to find a way to make it so the audio output runs through two channels on the mixer, to be able to use the crossfader and such. i have already messed around with asio4all and made it so that both pioneers can be used at once in traktor but again both tracks only come out through one channel in the mixer. also when i set the mixing mode to external i experience a lot of lag and feedback noise.
any help is appreciated an if you need any other information just ask
thanks
