-Possible Korean Web site support?
Yes that is possible, you need install the 3rd party language package for it.. but if I see from here
www.transifex.com/projects/p/jomsocial/
the korean is not possible yet and you need translate manually.
-Possible support for localized changes made during the upgrade?
What do you mean with localized changes? would you mind ellaborate more, please?
