Not even sure how to partition my HD lol
You could use GParted Live CD to partition your hard drive even after you already installed Windows.
http://gparted.org/livecd.php[...]I think Ubuntus Wubi installer could install them on the same partion or something like that, you could check it out.
Yes, Wubi creates a file on the Windows partition which will be mounted as a drive in Linux.
It has slightly less performance and I think there are problems if the shutdown does not finish correct (e.g. power failure).
What you also could do is running Linux in a VM like Virtualbox.
