Yes
*No. The original idea of "messiah" was "anointed one." Early Jewish peoples were not necessarily expecting one messiah. The idea of one, true Messiah is a later construct, usually referring to Jesus. If you are using Messiah as a name for the figure of Jesus, or possibly someone else, then it should be capitalized. If you are using the word to talk about early Judaism, it probably should not be capitalized.
