Without passing on your numbers here are some reason to partition:

  var -  A good idea, I think, especially with apache. It keeps a nimba style
         dOs from filling your disk.

  /   -  Without a var partition I believe var is in '/' and not user.
         /var/log, var/mail, var/spool/mqueue can grow. Your var size seems
         reasonable to me. /etc/named can grow if you run named. This is only
         an issue if you make / as small as possible. Note 5.x needs more space
         than 4.x which needed more than 3.x and we have 6.x as the new
         current. Its really hard to resize '/' without starting over. You can
         of course symlink out all of the stuff mentioned. I would make '/' 2
         times the current recommendation.

  swap - Some people use mfs for /tmp. Remember to add the size to swap if you
         do that.

  data - Separating data from /usr makes upgrading easier. Requirements on
         /usr have probably grown, maybe as much as for '/'.

I also assume you have a db partition for MySQL. A reason you may want that as
a separate partition would be to use the 5.x file system snapshot which might
make taking live backups possible. At least you could minimize the length of
the down. You could backup the DB on a different cycle and frequency from www.
I think good arguments can be made for combining the db and www partitions.
For example, if you undersize the db partition you would lose all those
advantages. I am not sure if innoDB allows for live backups. If it does and
you needed that I would use innoDB and one partition. On my main work station
I took the 4.x defaults of:

   /dev/ad0s2a      62M    45M    13M    78%    /
   /dev/ad0s2f      14G   7.8G   5.0G    61%    /usr
   /dev/ad0s2e      62M    17M    40M    29%    /var
   procfs          4.0K   4.0K     0B   100%    /proc

and I wish I had made a data partition which would make going to 5.3 a whole
bunch easier. All my servers have a data partition. On my laptop I take the
autoconfig and just start fresh when going to FreeBSD [n+1].0.

I hope this helps
