1- How does the ring work, did Sauron put all of his power in there to act as a intermediary so that if physicially died the ring would keep his lifeforce and his spirit on the physical plane?

Sauron did not put all of his power into the Ring, only about half of it. He did put enough of his power in the thing to keep him alive if he was defeated, but to destroy him if it were in turn destroyed.
