I will try it with the low level connection only. Do you think I should use the calibration program in the AR or calibrate with a test meter?

You don't need the extra output as you can always adjust the subwoofer level in the receiver's menu.

Initially, use the AVR to calibrate your speakers. After that, use an SPL meter to fine tune the system. The first part of A Guide to Subwoofers has guidelines on how to adjust the phase and crossover frequency.
