Sounds like the wait for an instructor was well worth it. I'd hold off flying by your self until you get a bit more time with the instructor. You need to learn how to handle a dead stick situation before you fly on your own. Probably another day or two with the instructor practicing landings and some simulated dead stick landings will have you set up. A couple of actual dead stick's thrown in probably wouldn't hurt as the plane will fly a bit differently with out the engine running. You also should practice a few advanced maneuvers while on the buddy box just to learn how to do them correctly, they you'll be all set. No reason to rush the last few lessons with an experienced pilot when they can do you a lot of good.
