Mwah... don't go overboard. rm'ing the whole thing doesn't take a
noticeable amount of time compared to *building* the tree, if you have
softupdates enabled at least.

I wouldn't use /usr/Xbld and /usr/obj - if you want a build partition,
just mount a /usr/bld, mkdir /usr/bld/{Xbld,obj}, and add symlinks where
appropriate. This is more efficient, too, as you would rarely need Xbld
and obj at the same time.
Similarly, I don't see the point in having /usr, /usr/XF4, and
/usr/local.
However, /virtualhosts suggests that you don't run Apache with chroot.
If this is the case, don't do that. ;-)
OTOH, I do strive to have one daemon - or, at least, 'function' per
partition, explicitly for the reason you mention below - protecting the
rest of the system from being brough to a halt by someone filling a
partition. So /var/mysql would be a good idea, though I personally
believe /var/postgresql to be a better idea.
In this vein, you could create a /var/log - as much to prevent the
logging daemon from the rest of the /var-using daemons as vice versa,
really, as log files can grow very fast under the 'proper'
circumstances.
Depending on functions, you may want to add /var/mail, /var/www, and so
on.

I don't really understand what you are trying to say here... but no, the
amount of accesses to a given file is independent on the partitions it
is on, all other things being equal.
