bassv2,
You are well on your way! Don't get discouraged at this point - these are early signs that you are learning. What everyone says is correct -
1) Don't get overly excited.
2) Stabilize yourself - I like to sit on the ground in my dream until everything is settled.
3) Remind yourself when falling asleep that when you become lucid you'll sit and rub your hands together. Tactile sensations will keep you in the dream.
