What are the three settings for on the rear shock? I have a ROCK SHOCK MONARCH RT3 AIR EYE TO EYE: 165mm/ external rebound and 3 position Flood Gate? It was set by a LBS and wasn't told much about the rear shock adjustment.

I bought a FS Mtn bike so I wouldn't be thrown off the bike as easy in rough terrain. My front Rock Shock only has 100mm travel and I just noticed that an ALL MTN bike has 140mm. Would 140mm help keep the rider on the bike better without being thrown off so easily?
