Hi,
How I did it was I unplugged the SATA connector from my old hard drive, then installed my new SSD and booted up the Windows CD and installer. Turn off computer and reconnected the SATA connector to my old hard drive and booted Windows from my SSD. Then in Windows I moved all the stuff I needed to backup from the HDD to the SSD, and then fully formatted my HDD, then moved all the stuff I backed up back to the hard drive. You can also backup your stuff to a USB or CD, because 60GB SSD won't be enough of course. You can also do this using the 2 hard drives; just move all into one and format the empty one, then move stuff back and format the other one.
Hope this helps
