Uh -- I think you are confused.  All security patches are issued as not
only as source code updates (for those that build from source) but also
as compiled binary updates via freebsd-update.

Judging by the output you showed, you've certainly managed to download
the -p4 binary patch set.  The 'No updates needed' message is just
telling you you've already got all the necessary update patchsets
downloaded.  The next step is running:

  # freebsd-update install

which will actually deploy those updates on your live system.  Which you
do mention doing.  Hmmm...

You aren't running a custom kernel according to your uname output, so
your kernel image should have been updated.  However, you would still
need to reboot after installing the updates. Until you do, programs like
uname that query the currently running kernel image will continue to
show the old version numbers.

Note that if a security update is just to some userland programs,
freebsd-update won't touch the OS kernel, so the reported version number
doesn't change even though the update has been applied.  In these sort
of cases, it's not necessary to reboot, just to restart any long running
processes (if any) affected by the update.  The security advisory should
have more detailed instructions about exactly what to do.  (The -p2 to
-p3 update was like this, but the -p3 to -p4 update definitely did
affect the kernel so a reboot was necessary.)

Yes -- that should be absolutely fine.  All 8.x versions of the OS
should be binary compatible, and any ports compiled for anything
labelled 8.2-RELEASE should work irrespective of the patch level.   In
fact, with a very small number of exceptions, ports compiled for any OS
version with a major version number of '8' should work.  Exceptions are
programs like eg. lsof(1) which accesses certain kernel internals in
non-portable ways.
