You don't need a kit. Though I too strongly recommend a clean install. If he is not going to do that fine.
Download the free Norton Ghost (NG) (probably special edition) from Samsung
(see video too, according to it you already have NG) and with both drives in the PC, boot up from the NG CD (ISO file). Transfer an HDD image over to the SSD. Shut down. Disconnect the HDD temporarily from the data and power connection. Boot up the SSD and make sure everything is going well. Then at some point--I'd wait at least a week to make sure the SSD is working--wipe the HDD and use as a secondary drive (might want to clone an image of the drive if he has a backup drive before doing any of this.
As someone mentioned you can do this with Acronis (trial) or Macrium Reflect free (my preferred) installed on the boot drive and many more drive image makers that have
intelligent sector imaging.
