150Hz sends less of the bass to the speaker, and more to the sub, as compared to a setting of 80Hz. Crossovers are not "brick walls", but generally the receiver will send any bass below the crossover frequency to the sub. So, for instance with the center channel, if the crossover setting is 120Hz, any bass in the center channel of the movie you are watching will get sent to the sub instead of the center speaker.

Audyssey measures it for you.
Bass above 80Hz is said to be "localizable", which means that you can tell which speaker the sound is coming from. Most sound you hear from the speakers is localizable, so perhaps it is more clear to say that bass below 80Hz is usually NOT localizable -- which means you can't really tell where it is coming from in the room. It is sort of surprising, but it's true -- you can't really perceive where low bass is coming from, even if you have the sub in a weird spot, like behind you on one side of the room.
So, the issue is that your speakers don't have much bass capability, and you will probably be able to tell that the bass is coming from the sub, even when it is "supposed" to be coming from one of the other speakers. You could reduce the crossover frequency settings, but I don't recommend that since your speakers can't reproduce the lower bass sounds at a reasonable level -- reducing the crossover frequency settings will make "holes" in the response of the system. I think it is better to accept the Audyssey settings and let the bass go to the subwoofer. Since most sound comes from the center channel in tv and movies, I would try to position the sub as close to the center speaker as you can (as opposed to far off to one side, or in the rear of the room).

What would the difference be between -8 for front and center and -6 for surround compared to 0 and +2? It would seem like the sound would be the same you would just have to turn the former up louder?
I don't know why Denophile suggested that. I agree with your assessment of the effect, which is that there would be no difference except in how much you have to turn the volume knob to achieve a given "real" sound level.

I dont want to spend any more money, but if I can get this sound setup disc or something similar for free online I would be glad to give it a whirl. Does it help you set up the Tone and the Volume?
You can probably find some free test tone discs online. However, I would just accept the settings that Audyssey has determined for you and optimize around those settings (e.g. getting the sub close to the center of the room).
