ext3 is still the default as of 6.0.3 Squeeze.  I remember this
because I net-installed it on a new server yesterday.

http://wiki.debian.org/Ext4  suggests the installer allows ext4 as an
option, though.

It's also possible to convert an existing ext3 filesystem to ext4.

If you have a large amount of RAM, you might want to consider
running without swap (create the partition, but only swapon when
you need it, for huge complies, etc.), and use a tmpfs RAMdisk for
things like browser caches.  Or put these on a standard HD if one
is present.

This can greatly reduce unnecesssary writes to the SSD, which I
still try to minimize even though modern devices are supposed to
have such good wear-leveling that it doesn't matter as much as it
once did.

None of it's really necessary... just a matter of how obsessive you
want to be about minor optimizations ;)
