My advice would be to do some solo flights to get used to flying without an instructor and build some confidence before taking passengers. Most clubs will sign you out to go solo while waiting for your license to come through so this is a good opportunity to do it.
On the first few flights where you take a passenger up I'd make them something you've done before, eg a local flight or a landaway to somewhere you're familiar with - don't make life too difficult for yourself by going somewhere new at the same time.
