rc stands for Release Candidate, and should be fairly close to the "real
normaly rc's are fairly stable

CVS (IIRC Concurent Version System) is a system for developers to have
their updates coordinated properly. This is always (nearly) work in
progress, so you should
only use it if you're into developing. 
As for the other two, pre or beta? I would always look at the date, and
take the
newest, or one that is explicitly labeled stable.
Don't know if there is a FAQ/Standard, I guess its a matter of taste
