If you have a regular, single-computer retail install disc of Leopard (which you should if you bought it) then you can either clone your existing data directly to the new hard drive from the old one using a tool like Carbon Copy Cloner plus an external drive case/adapter, or just reinstall Leopard on the new drive and copy your data over from backups (or however you were planning on doing that). The OS and its installer don't do any kind of authentication/hardware lock-in, so you're not going to get asked to reactivate it like with Windows.
