cool! great questions. 

    as to swap, my incomplete answer for you is a single 1G 
swap partition is what i have: 
sda1 on / 
sda2 swap 
sda3 on /home/ 
    Red Hat has some docs that claims that over 2GB is 
useless swap space. if you really need lots of swap space, 
have multiple <= 2GB swap partitions. 
    I've never had a problem with a single 1G swap partition. 

    as to /var/ i used to use /var/ for a separate partition, 
but learned (sadly, as usual) not to do that: /var/ stores 
system files that may be needed unpredictably and 
immediately. should the filesystem for /var/ be unavailable, 
there's no predicting what bad things might happen. i don't 
like pain at all, am highly avoidant, and now make sure /var/ 
is part of the  /  filesystem. 
    i no longer bother using /var/log/ or /var/www/ for 
separate mount points (not on my laptop, for sure). you can 
set /var/www/ as a separate mount point with no risk of 
system functionality if the filesystem were unavailable. 
    in olden tymes /var/www/ was the commonly used directory 
for web site storage (hence a separate partition/file system). 
i understand that /opt/ or /srv/ are now the new, modern, hip 
directories to use, and having them as mount points makes 

    as to the size for the  /  filesystem, i am overly liberal, 
i'm sure, but that's due to my natural paranoid leanings. the 
fear is that i might add more software that has more libs and 
docs and whatever that loads up storage. depends on how much 
more software you expect to add. 
    note that /usr/share/ has a lot of stuff in it, and none 
of it is critical to system functioning, so that's a candidate 
mount point to reduce the use of the storage you've allocated 
for the / tree. 

    if you're in the more-patitions-is-good-paritioning camp, 
consider using /usr/local/ as a mount point.
