Depends a lot on what you want to do, but one reason is that if one
partition fills up, it doesnt bring everything else down.

Its a good idea to keep /usr seperate because whenever you install a
new package, most of it goes there. A good trick I found was to mount
/usr read-only by default. That way, it increases security and reduces
the chances of corruption.

Should be fine if its more than 2 x RAM and you really need it.

It can grow. Should be safe to keep it small though, unless your mail
queue is very busy or your packages write most of their data there
(default install of Postgres on RH keeps the DATABASE there).

That depends on where most of your software gets installed. After doing
a standard install, i build most packages and keep them in /usr/local,
so its bigger than the rest of /usr.
