What are you recording? Bands? Drums? Just yourself? That all comes in to play mostly with the mixer and monitoring possibilites.

First things first, the Mixer main outs go into the Saffire line inputs.

The Saffire outputs need to go to the Big Knob inputs, I'm pretty sure.

Big knob outputs to the monitors.

Mic into the preamp of course.

If you have to use the mixer then the Preamp outs go into the mixer line inputs.

Saffire Firewired to the laptop.

Keyboard and Guitars to the mixer.

I think you know all this. Just take it one cable at a time.

Be sure you actually need a mixer. If you have less then four inputs take it out of there.
