Clearing isn't really intended for use with deferred entry. You can try to apply to unis, but they may not be willing to offer you a place. You would have more choice if you were to reapply.
Yes, just to confirm, Clearing this time round is just for 2009 entry. If you don't get the grades you can reapply in Sept-Jan and then Clearing 2010 will be your ultimate back-up choice.
