sam didnt wear the ring though. is his life extended because he held the ring? were there actually more ships that left after frodo and gandalf left?

anything else happen after frodo throws the ring into mount doom i should know about?

i heard that the elves and dwarves fought the orcs at the same time the humans did, but it wasnt mentioned in the movie. did the books cover this at all or not really?
