There are a few ways to do this. One way would be to install the 500GB drive, set it as the boot drive in BIOS and then either install the OS from recovery disk or from OS installation disk (if you have full version OS disk). Then install all programs you had on old hard drive from CD/DVD or whatever the source was. Last step is copying over the files you want to keep from the old drive onto the new one.
Another way would be to create a disk image of the old hard drive using Norton Ghost or Acronis or something similar. Then just install the new drive and restore your previously saved image of the old drive to your new drive using the same software you used to create the image (Norton Ghost, Acronis, whatever...) This way you won't have to reinstall your OS or any programs. You will need a relatively large storage device (external would be best) to store the image during the process, though.
