You should watch the Wyeast video on starters. Anything over 24 hours
is not good for the yeast. Most new growth is done after about 18 hours.

Chill the starter so the yeast drops out of suspension and then dump most of the wort off the top. You...
I'd add two or three more vials to ensure a healthy fermentation. And your probably going to need a blow off tube. You need to add the yeast today so get it from a local home brew shop. You can also just add a packet of US-05 since it is the same yeast as WLP001.
I would toss that batch. Glass is the last thing you want imbedded in your throat. I doubt you can filter out the tiny shards and if it gets into your throat you'll need surgery to have it removed.
