Install Sharepoint on the new server and during the install, point your new front end web server to your back-end SQL. if you are running a stand-alone box and are looking to move that, Install sharepoint on the new box and then use stsadm -o import command http://technet.microsoft.com/en-us/library/cc261866.aspx or stsadm -o restore command http://technet.microsoft.com/en-us/library/cc262087.aspxto import or restore your files into a blank site or site collection on that new install. If you are running on a stand-alone box, now would be a good time to switch over to one front end and one back end and get your farm started. Your users will be much happier with the added speed that this will provide. When you perform the import command or the restore, you will need to map a drive over to your old box where the backups reside or copy the entire contents of the backup files to the new box, before running the stsadm command.
