How does the Wubi installer work? Which partition does it install Ubuntu on? If it's on the Windows partition, where is it in the filesystem?

Wubi installs just like a normal "windows program". (you can uninstall it easy to = the normal way). It is considered by Windows as a second OS a boot time. You have no partition - just space of Windows (on the C partition). Windows is not able to see what is in that space. Ubuntu can see the complete windows installation on the C-drive. But a good advice: just try it ( as wubi no more and not to long). Make a specific partition for Ubuntu and install it just on that partition. There is Gparted (you can download it for free) for making the partitions. This methode make your Ubuntu installation independent from Windows. Good luck
