Shrink Current XP Partition to Fit on smaller SSD

Please correct me if I'm not posting this in the appropriate forum.

I currently have win xp installed as only my only boot disk on a 160GB Partition of my standard 640GB hard drive. I will uninstall the large games that are taking up a lot of space on it, and get it so total disk space used is <64GB. It is a homebuilt desktop computer, not a notebook.

What I would like to do is shrink this this 160GB partition down to 64GB so I can fit it onto a new 64GB SSD. Then use that 64GB SSD as my new boot disk. Would this be a relatively seamless operation? How would I go about shrinking the partition size, then cloning the disk? Anything I should know before doing this?

Thanks guys.
