RE: Landing Speed
A good thing to do is to pretend that the runway is about 50 feet higher than it actually is. Practice landing on that imaginary field up there; it will tell you how fast or slow to go, and what kinds of rudder and elevator imputs to put in. Then after a few passes, make the field 20 feet high, and so on until you're comfortable with how the plane reacts. No matter what you read in here about specifics, every plane and wind condition is slightly differient, so the best way to learn this skill is to practice. A strong headwind usually requires a few more clicks of power on final, as too little power will make the plane wallow around a bit. Once you have the plane down close to the runway, you can back off of the throttle, as the plane should slow down quicker in a headwind than not. Again, practice up high a bit to find out the exact inputs you need to make.
