No, that's not correct, all of the ciphers will be available in TLS 1.2,
because they are all defined for TLS 1.2.  TLS 1.2 inherits all the
ciphers that come from previous versions, including those ciphers
introduced in SSLv3, TLSv1.0, and TLSv1.1.

GCM is understood to be a more secure symmetric cipher than many of the
others options, so i would recommend using it if you have the
opportunity, though.
