Yes, set the sub/main speakers crossover down to 80hz. 150hz is too high because the sound from it is directional at that frequency.
Yes, the sub will reproduce frequencies below 80 hz and you mains will take over at 80hz on up. Your mains are rated down to 60 hz so there won't be a problem with the lower crossover frequency.
Enjoy you new toy.
