I would suggest you partition your volume like this.
It is extremely easy to LVM to expand a volume, so make all your logical volumes the small, and leave yourself lots of free space on the volume group. When you need more storage allocated it as needed.
See the LVM howto for details on LVM.
You can use a shared /boot partition for multiple installations, but it will require some manual tweaking of your bootloader configuration, and you should keep backups of those files as you are doing your installs.
Unless you are really low on memory, you might want to skip setting up any swap.
