can i just copy everything to an external HD? then copy it to my new one?

also am i going to have to install leopard on the new HD that i get? or will it be installed when i copy all the files from the external?

you can use any of the apps chscag has mentioned to clone and back-up your drive.

Then you can do a clean install of Leopard (recommended) - wiping all your old stuff off the macs drive

Then you can use Migration Assistant in Utilities to migrate all your stuff (files apps music etc) to your new leopard installation from that back-up drive you made
