1. Not necessarily, but in general, sony images are well-saturated - the usual complaint is "over-saturated". Is your monitor poorly calibrated? If you push saturation to +2 or +3, you may see some noise in certain scenes. All depends on lighting.
2. The right mode for the right purpose. All sony AF systems are very intelligent, though I usually save the camera the effort and set it to whichever mode i need at the time. For a "focus and recompose" requirement, usually only AF-S as i don't want the camera to try to be "smarter" than me.
