I've just set up a net book with SSD, and read a bit about it. Journaling is in general not a good idea performance-wise on a SSD, but it can be disabled. I used ext4 with disabled journaling, like this guy:
You can use ext3 if you like. But don't use a swap partition on your SSD disk, add more RAM instead to your machine.
ext2 doesn't journal at all, and therefore it's better for a SSD disk. But this comes at the cost of a less secure file system.
So if you are more concerned about wearing your SSD down with ext4/ext4 you should use ext2, but if you want journaling you should use ext3. I'd recommend using ext4 because it has checksummed journaling which is safer.
SSD is pretty reliable these days, or so I've read, so I doubt if journaling would be a problem. One thing you can do to reduce access is to edit the mount parameters in /etc/fstab by adding noatime,nodiratime
