With that, you could create a large partition on each drive, combine them into a "Logical Volume Group", and then split that LVG into multiple "Logical Volumes" which look like partitions, but can be resized and reassigned dynamically.
The installer doesn't support LVM, and I haven't seen a Debian-oriented HOWTO, but what I did was to create one smallish partition on one disk and one which takes up the rest of the disk. Install the base debian system onto the small partition (I made it 500Mb, but you could probably get away with half of that). When it gets to selecting packages, stop and deal with LVM. You need to make sure your kernel supports it (Must be 2.4, and must be configured.) Install package "lvm10" for the tools. ~ You can then create logical volumes for /home, /usr, /var. Boot into single-user mode and move the existing files into the new volumes.
It doesn't matter now what sizes you use for the partition. Make them as much as you need to start with, and when you need more it's easy to make them bigger. (If you put reiserfs filesystems on them, you can make the filesystems bigger without even unmounting them).
With multiple disks, you can use "striping". I've not done this as I have only one disk, but it's in the documents referred below.
There's a lot to all this, but if your aim is to learn more about linux it's a useful thing to find out about.

example of moving files into a new filesystem (once you have created your volume group):
(in single-user mode ( boot with the "single" kernel command-line option ) )
lvcreate -L 1G -n usr myvg01 # to create a logical volume mke2fs /dev/myvg01/usr # or you might prefer ext3 or reiser mount /dev/myvg01/usr /mnt cd /usr tar cf . | ( cd /mnt ; tar xvf - ) # there are also options on cp that ~ # would achieve the same thing. umount /mnt mv /usr /oldusr mkdir /usr mount /dev/myvg01/usr /usr
rm -r /oldusr # If everything succeeded.
