When I use CVS I see that there are always extra files like "Entries", "Repository", and "Root". I've heard that there is a flag ('-R'?) that will prevent these files from appearing on my local drive, but I wonder if that would cause problems when I try to commit my changes.
Does SubVersion have extra files like this?

Marilyn, -R means to operate recursively, so that wouldn't be it. -r is to create a sticky version. That means you can't check in code against it (the version.) As far as I know it still creates those special files though.
If you were able to not create those files or ran a script to delete them, CVS wouldn't know where to check the files in again. I haven't tried it, but I suspect it wouldn't work.
Subversion creates similar files. The repository information has to go somewhere. The difference is that with svn, those files are in a directory named ".svn", starting with a dot. On UNIX-like systems, this is a hidden directory. I don't know about svn on Windows -- whether the directory is hidden or not.
I've been working with the subversion-based Apache Directory Project, and its Subversion files appear to be more intrusive than that, but maybe it's just an artifact of whatever the heck they think they're doing.
The way to get a copy of the CVS code without the CVS info attached is to use the CVS export command.
Of course, without the CVS info in it, there's no easy way to update CVS against the exported copy, but the purpose of CVS export is to ship stuff out to places that don't want/can't use those CVS files in their copy of the project.
