That's mostly true but two more important thing about the Messiah are that before he comes there will be a great war called (in hebrew anyway) "Gog U'Magog" in which most of the worlds population will parish. The second thing is that when he comes all the bodies will roll be themselves to the Holy land and then come back to life. That is by the way the reason that many jews come to Israel before dying, do their body won't have to go all the way back there when the Messiah does come. Ezekiel prophecised this in his prophecy called "The Prophecy of the Dry Bones".
"The hand of the LORD was on me, and he brought me out in the Spirit of the LORD, and set me down in the midst of the valley; and it was full of bones. 37:2 He caused me to pass by them all around: and behold, there were very many in the open valley; and behold, they were very dry. 37:3 He said to me, Son of man, can these bones live? I answered, Lord GOD, you know. 37:4 Again he said to me, Prophesy over these bones, and tell them, you dry bones, hear the word of the LORD. 37:5 Thus says the Lord GOD to these bones: Behold, I will cause breath to enter into you, and you shall live. 37:6"
