The big question I have concerns setting up my subwoofer (Seismic 10) so it correctly works with ARC setup. On the back of the sub, what should I have the following knobs turned to: phase alignment, subwoofer cut-off frequency, bass coutour, and subwoofer level? Once I have the sub set, I am of the understanding that ARC will take care of all other settings, levels and measurements, unless I am completely not understanding it.
I have all new cables I am using for my setup: High Speed HDMI for future 3D use, 12 Gauge cable for the fronts (Studio 100s) and center (690). I had to purchase a Keyspan USB serial adapter since my MacBook does so not have a serial port.
Is there anything else you would suggest?
Thanks for volunteering your help and thanks in advance for any advice.

Just a tip...
For the subwoofer channel, I would eventually use the analog/continuously-variable filter in the Seismic instead of the on-board bass management. Digital filters only offer adjustment 'steps,' so you will most likely choose 60Hz; 80Hz; or 100Hz... A good starting point (especially since you can toggle through the options with the receiver's wireless remote) when you are shaking things down... But eventually I would set the MRX's low-pass filter to it's highest setting (150Hz), and use the filter in the Seismic to dial in (pun intended) the best corner frequency.

ARC wants to hear the full capability of the subwoofer, without artificial limitation at either the high or low frequency end. ARC will then determine the best way to use that subwoofer in conjunction with the main speakers.
Part of the ARC solution will be assigning a crossover frequency to the sub, but keep in mind that the way that crossover blends with the crossovers of the mains is refined by the room correction processing. This mitigates your concern about the step size of the available crossover frequencies.
