Lots of good advice. I try not to think about too many things. Practice one or two until it becomes second nature, and then focus on one or two more.

Look at where you want to exit the turn
Brake before the turn, hands off the brake while turning unless you have a major emergency
Steer primarily by leaning bike
Outside pedal down on turns.
Weight on outside pedal
Keep body vertical while bike leans

and finally - increase body mass.

j/k on that last one.
