It is a bit late for your laptop now, but before playing around with partitions it is a good idea to take a complete "image" of your hard disk so your can recover it at a later date.
A product like Acronis True Image can take a complete "snapshot" of your hard disk and save it to another hard disk (maybe an external hard disk plugged into a USB port).

I have 2 hard disks inside my PC desktop.
After I have done a new "clean" install of Windows I use Acronis to save an image of the Windows hard disk to the second hard drive.
If at any point my main Windows hard drive gets a problem (virus or whatever) or I just want to "start again" I just use Acronis to restore a "new" version of Windows in place of the old one.
That way I can "reinstall" Windows in about 10 minutes.
As I said, bit late now as you have lost your recovery partition, but it is not too late to do a "backup" of your Vista partition in case something goes wrong.
