With 640GB, I'd go ahead and set 8GB of swap in case I ever did want to
hibernate. If you're sure you'll never need it, 2GB sounds good to me.

/ depends on what other partitions you have. On servers I'm a fan of /
/tmp /home and /var with /var accounting for 80-90% of the space. On a
home server I do the same with a larger /home though I usually toss
music, movies, etc into /var and share via Samba to keep them out of my
personal home dir.

Don't forget Mysql ends up in /var/lib/mysql as well. However it is easy
to point Apache to your homedir with a vhost I don't recommend moving
Mysql around unless you have some experience since it can be a little
hard to troubleshoot or cause updates to fail in certain distros. 10GB
for /var is reasonable though I'd lean towards 20GB if you do a lot of
development and large data sets in Mysql.
Two things you should do to your Mysql instances are add these lines to
your my.cnf under [mysqld].
max_binlog_size = 100M
expire_logs_days = 10
This will keep binary logs from filling your /var partition. I don't
recommend turn off log_bin as having them can help Mysql recover in
Not very laptop central, but hopefully some of this is useful for you.
