cvs2svn worked fine for me during a CVSNT->SVN migration some years ago.
Subversion stores access permissions in a special configuration file
on the server, so you'll have to re-create users, groups, and their
access rights in the SVN server's configuration:
Generally, I would recommend scripting the entire data migration process such
that it is repeatable. Then you can iterate the conversion process and allow
users to test the new system well before it goes live. Keep iterating until
you get a result that is acceptable for production use, then switch.

You could use externals for this purpose:
These can be configured post-migration in SVN, and/or inside SVN as a
post-processing step during scripted data migration. Externals basically
configure a 'repository URL' to 'local directory' mapping which the
SVN client follows when it performs a 'checkout' or 'update'.
As noted in the SVN book chapter I linked above, externals should
always use 'relative' URLs rather than absolute URLs, where possible.
Relative URLs are resilient to potential future changes of most URL
components, such as the SVN server's hostname.
I would discourage use of externals to handle complicated dependency chains.
Externals are good enough if the dependency relationships are of a simple
variety. But if you find yourself using more than a handful of externals,
you're probably better off using a dependency management tool that works
above the version control system (e.g. in the build system).

Yes. See http://subversion.apache.org/packages.html#windows for a
couple of options.
