umm, let's see.
'cvs status' gives you couples of information about each selected
file, including the working revision and the repository revision, but
neither of them show the newest repository revision. (I tested rolling
back to an elder revision. This got me a sticky tag, but now I can't
see if there is a newer version on the server. Maybe you can if the
version changes on the server before you update (and without stickies,
of course)
If you need that for scripting, you can get it with 'cvs log'
It shows the servers newest revision on one of the first lines, called
"head". (Head means no branch, don't know if that's the same for svn).

ah, that's an easy one:
'cvs up -rRevision' or 'cvs up -DDate' (I think it does not matter if
you do a blank between the option -r/-D and the actual identifier).
But, it set's this "filter" as sticky, so a normal update afterwards
(even on the whole directory) will not get you the newest version, but
the stuck one. To get rid of stickies: 'cvs up -A'
If you want to revert to the newest avaiable repository-version, 'cvs
up -C' will get a clean copy.

For a "normal" update, I strongly recommend to do 'cvs up -Pd': It
creates new directories if something new's been added and it deletes
empty directories if they've been purged.

uh, wait. double-check the things I've been saying. I was referring to
cvsnt, not cvs, altough the differences should be small.
