Don't scrap it. Unless you need this container really badly for something, let it roll man. If it's in a nice carboy transfer it into a 1 gal Poland Spring bottle and do it there, and use your carboy for a second, more confident batch.
Dropping the lid in isn't good. The StarSan isn't the end of the world, though I use crappy bottom-shelf vodka to fill my airlocks since this sort of thing happens to me a lot more than I would like. Especially since I've started using a plastic Better Bottle - when you move it, the bottle deforms and can create suction in the airlock. I've dropped a bit of vodka into my blueberry batch already, but I'm not concerned.
As for the yeast, take gravity measurements and wait. If there is no visual or measurable evidence of fermentation, just re-pitch.
