not sure how quickly you checked the oil after shutting it down but it takes a few minutes to settle back down in the crankcase once you turn it off. Take a buddy with you and let him hold the bike straight up while you check the level in the site glass. It doesn't have to be level full at the top, just between the lines.
As far as the high RPMs, unless you were "floating" the valves you most likely didn't do any damage. Plus I believe these things have a rev limiter to prevent just this such thing.
