Ijack you are gonna confuse the poor guy. optimizing an SSD can get very complicated. especially when you are dual booting
I'd recommend using btrfs instead of EXT4 but I'm not sure if its supported in the standard Ubuntu 12.04 installer or if you need to use the alternate installation cd. Its nice to see the next Fedora 18 will use tmpfs to store the tmp files in ram instead of the hard disk.
Oh you dont need to make a swap partition on the SSD. just make a single swap partition on the hard disk and ubuntu will use it.
