US-122 audio/midi questions??

I finally got my Tascam US-122 working w/ my Korg NS5r(sound module) now im just waiting on my mixer so I can record in it. Will I need to MIDI Clock anything if its getting recorded into my Acid Pro 6 into the mixer?? And I got playback sounds comeing from the US-122 now when I get the mixer will it come from the mixer tru monitors or US-122 tru monitors? Should I hook 2 1/4 wires to stereos on both end of the mpc and ns5r and put in mixer so when I mix it in the PC?

Bump. I posted 2 different topics and no seems no to answer to neither of them.
