Its been a very long time since Ive done this (just came back to pose a few days ago) but I will try my best to help you out.

Gravity
This setting is not actually the amount of gravity applied (such as the name implies) but the speed at which the hair will naturally move along the global Y axis. negative numbers move the hair down, positive up.

Spring Strength
this is the setting for how springy the hair is, such as curls bouncing a little after they move.

Air Dampening
This is how much resistance the air has on the movement of the hair. higher numbers will start to make the hair look like its moving through liquid

Spring Dampening
This setting sets how much the momentum of the hair is reduced while it is springing. if you set this to 0, the hair would take a VERY long time to stop moving, and it would rely almost entirely on the air dampening setting.

Bend Resistance
This is how hard the hair is to bend. higher numbers make the hair more stiff (as if it has gel in it) and lower number numbers make the hair more like silk in its ability to fold.
0.84 is about average, but if your working with styled hair, a higher setting of aorund 0.88-0.92 will help keep the hair in its correct shape this setting is extremely sensitive.

Position Force
This setting is key for styled hair, this sets how much the hair "wants" to return to its original position. too high a setting will stop the hair from moving all together unless something physically interacts with it. too small a setting will cause the hair to struggle to return to its original position due to air dampening and gravity settings

Root Stiffness
This setting is basically Bend Resistance, but just for the first part of each hair. higher numbers make the hair stiffer. the lower you set this number, closer to the head the hair will start to bend. this setting is key because to low a number, and the hair will sit unnaturally on the head. too high, and the hair will start bending too far away. looking strange.

Root Stiffness Falloff
This setting is the distance along the hair that the Root Stiffness setting no longer takes effect. This setting works in direct relation to the one above, lower root stiffness, but higher falloff can give the same effect and higher stiffness with a lower falloff.

I hope this helps some. If I get time, I will do some examples when I get home
