After burning SD card, touch ssh on boot partition to enable ssh.
Default ssh credentials: pi : raspberry
Remove redundant stuff:

Warning: this will probably break something. If you need sound, don't remove the "alsa" packages

apt-get purge might delete these for you:
sudo rm -r /usr/lib/xorg/modules/linux /usr/lib/xorg/modules/extensions /usr/lib/xorg/modules /usr/lib/xorg
rm -r ~/Desktop
rm -r ~/python_games
do an update/upgrade:
sudo apt-get --yes update
sudo apt-get --yes upgrade
It's a good idea to regenerate the ssh keys rather than use the ones on the image.
sudo rm /etc/ssh/ssh_host_* && sudo dpkg-reconfigure openssh-server
You may need to clear out the old keys in .ssh/know_hosts on the client:
ssh-keygen -R [IP]
