While you have that front clip off replace the water pump with a welded gear style. The harmonic balancer has to come off to get the water pump off. It's a pain to replace it with the front clip on. Lisle sells a kit for holding the flywheel and it comes with the socket for the harmonic balancer. When the balancer comes off inspect the pin on the shaft to ensure it wont sheer later.

Also remove the crankshaft position sensor (Bottom passenger side of the motor) and check the reluctor gear for any play. Now is the time to inspect it because you can see it easily. Probably no issue with it but it's worth the 5 minutes to inspect it because of the front end collision.

And finally, the plastic part by the alternator that broke was the PCV.
