Partition Suggestions

[azz]

For a desktop, there is no big reason to use more than one partition. 
Also, ext3 is just fine.

Also, you can tell your bios to boot from the second HDD.  Install
Ubuntu this way and tell it to install grub there.  It will still
detect your windowsinstallation and add it to the list.  If you ever
want to switch back and remove Linux, tell your bios to boot from the
first drive again.  Simple.
