I have a laptop with an 80GB SSD and 500GB HDD. I currently have Windows installed on the SSD, and a 400GB data partition for Windows on the HDD. I set aside 100GB on the HDD to try out Ubuntu, and I'd like to make it my primary OS and switch it over to the (much) faster SSD.

How could I go about getting my Ubuntu setup moved over to the SSD? I have a 120GB USB hard drive I can use if necessary for getting through it.
