Yeah, I'd say go around and make sure all the ignition connections are still in place, ie. the coil wire. Also, take a look to ensure that the distributor isn't cracked or what-not.
More importanly, I'd suggest going over your starting system and battery.
You said that the starter clicks, does it crank as well? As I recall, the starter grounds right through its mount. Take a look to see that the starter is seated properly and that the bolts holding it in place are tight (there are two, if memory serves me correctly). In the past I've had intermittent starting problems due to loose starter bolts. Also make sure that the positive side is all in place.
Another place to look is the battery. Make sure both leads and terminals are squared away. Also, if you took a serious hit, your battery's cells/plates may have been structurally compromised. Try swapping in a different battery and see if that helps at all. Be mindful of leaking acid as the battery's case may have been cracked as well!
That's what's coming to me off the top of my head. Hope it helps.
Later.
