stamina and chakra are the same thing the databook states this

lee still has to develop his chakra to use his speed

chakra is spiritual and physical energy combined so no matter what there powers are physical in nature if lee didn't have chakra he wouldn't be able to do anything in a fight

when lee challenged sasuke to a fight and there arms met sasuke specifically says that lee's chakra is strong

the only difference is lee uses chakra to enhance his muscles he doesn't use it for ninjutsu but none the less he still uses it and can use up his chakra and no longer be able to fight

it doesn't matter there is no sound to us they clearly make sound since shira had to develop a technique to cover up the sound created from there movements

the no sound is simply an artistic matter just like how you never hear the sonic boom when flash runs unless he is extremity breaking the sound barrier
