As for the first question, 'pkg_version -v -L=' should tell you what needs
upgrading.

For the second part, you've already had some portupgrade suggestions, I have
a new port management tool in sysutils/portmaster that you might take a look
at as well. You can either choose to (recursively) rebuild a single
application and its dependencies, update everything that needs updating, or
update everything.
