Alright heres the deal, my band has started the recording process, and we are new to this, but not new to the point where we dont know anything were doing. Were recording with an Audio-Technica condeser special edition mic and a digital interface so that we have a good sound card, and we are using adobe audition.

I have a little mixer called the Behringer Xenyx 1202 FX
 
What I would like to do is monitor my vocals with the effects from the mixer along with the output from my computer's sound card through the headphone Jack on the mixer.
But when recording, only record the dry vocals back into my computer. I have tried many things but nothing is really working.

I am recording some dry guitar tracks tonight and am getting more hiss than I want when going back through the pod. I have a les paul going straight into an Avalon 737 then into the mixer. I am coming out of an aux, balenced, into a radial JDI then unbalenced into the pod. The pod then back into the mixer. I am just getting too much hiss on the pod sound. Am I doing something wrong?

My guitar signal is going into my soundcard and is then being processed by Cubase with vst/dx plugins in real time. I am unable to mute the dry signal for some reason. All i want to hear is the 100% wet, processed signal, but can't seem to do so. I have a SBLive, which I a am using the APSLive ASIO drivers.
