What is the correct fret hand position?
The thumb of your fretting hand should rest behind the neck of the guitar placing it approximately between your first two fingers. Make sure to bend all your knuckles (1st, 2nd and 3rd). Use the tip of your fingers to press down the strings and place them as close to the fret as possible.
Where should you rest right hand when playing guitar?
Rotate your right hand at the wrist so that the fingers fall perpendicular to the strings and your thumb stays about 1 1/2 inches to the left (from your vantage point) of your index finger. Rest your right-hand thumb and fingers (index, middle, and ring) on the 6th, 3rd, 2nd, and 1st strings, respectively.
